### Dependencies

#### Required:

* [FileSaver.js](https://github.com/clarketm/FileSaver.js/)

#### Optional:

* [jQuery](https://jquery.com) (1.2.1 or higher)
* [Bootstrap](http://getbootstrap.com/getting-started/#download) (3.1.0 or higher)

#### Add-Ons:

In order to provide **Office Open XML SpreadsheetML Format ( `.xlsx` )** support, you must include the following third-party library in your project before both [FileSaver.js](https://github.com/clarketm/FileSaver.js/) and [TableExport](https://tableexport.travismclarke.com).

* [xlsx.core.js](https://github.com/SheetJS/js-xlsx) by *SheetJS*

> Including `xlsx.core.js` is **NOT** necessary if installing with [`Bower`](#install-with-bower) or [`npm`](#install-with-npm)

```markup
<script src="xlsx.core.js"></script>
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
```

#### Older Browsers:

To support legacy browsers ( **Chrome** < 20, **Firefox** < 13, **Opera** < 12.10, **IE** < 10, **Safari** < 6 ) include the [Blob.js](https://github.com/clarketm/Blob.js/) polyfill before the [FileSaver.js](https://github.com/clarketm/FileSaver.js/) script.

* [Blob.js](https://github.com/clarketm/Blob.js) by *eligrey* (forked by *clarketm*)

> Including `Blob.js` is **NOT** necessary if installing with [`Bower`](#install-with-bower) or [`npm`](#install-with-npm)

```markup
<script src="Blob.js"></script>
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
```

## Usage

### JavaScript

To use this library, simple call the [`TableExport`](https://tableexport.travismclarke.com) constructor:

```javascript
new TableExport(document.getElementsByTagName("table"));

// OR simply

TableExport(document.getElementsByTagName("table"));

// OR using jQuery

$("table").tableExport();
```

Additional properties can be passed-in to customize the look and feel of your tables, buttons, and exported data.

Notice that by default, TableExport will create export buttons for three different filetypes *`xls`, `csv`, `txt`*. You can choose which buttons to generate by setting the `formats` property to the filetype(s) of your choice.

```javascript
/* Defaults */
TableExport(document.getElementsByTagName("table"), {
  headers: true,                      // (Boolean), display table headers (th or td elements) in the <thead>, (default: true)
  footers: true,                      // (Boolean), display table footers (th or td elements) in the <tfoot>, (default: false)
  formats: ["xlsx", "csv", "txt"],    // (String[]), filetype(s) for the export, (default: ['xlsx', 'csv', 'txt'])
  filename: "id",                     // (id, String), filename for the downloaded file, (default: 'id')
  bootstrap: false,                   // (Boolean), style buttons using bootstrap, (default: true)
  exportButtons: true,                // (Boolean), automatically generate the built-in export buttons for each of the specified formats (default: true)
  position: "bottom",                 // (top, bottom), position of the caption element relative to table, (default: 'bottom')
  ignoreRows: null,                   // (Number, Number[]), row indices to exclude from the exported file(s) (default: null)
  ignoreCols: null,                   // (Number, Number[]), column indices to exclude from the exported file(s) (default: null)
  trimWhitespace: true,               // (Boolean), remove all leading/trailing newlines, spaces, and tabs from cell text in the exported file(s) (default: false)
  RTL: false,                         // (Boolean), set direction of the worksheet to right-to-left (default: false)
  sheetname: "id"                     // (id, String), sheet name for the exported spreadsheet, (default: 'id')
});
```

> **Note:** to use the `xlsx` filetype, you must include [js-xlsx](https://github.com/SheetJS/js-xlsx/blob/master/dist/xlsx.core.min.js); reference the [`Add-Ons`](#add-ons) section.

### Methods

TableExport supports additional methods (**getExportData**, **update**, **reset** and **remove**) to control the [`TableExport`](https://tableexport.travismclarke.com) instance after creation.

```javascript
/* First, call the `TableExport` constructor and save the return instance to a variable */
var table = TableExport(document.getElementById("export-buttons-table"));
```

#### [`getExportData`](https://tableexport.v3.travismclarke.com/examples/exportButtons.html)

```javascript
/* get export data */
var exportData = table.getExportData(); // useful for creating custom export buttons, i.e. when (exportButtons: false)

/*****************
 ** exportData ***
 *****************
{
    "export-buttons-table": {
        xls: {
            data: "...",
            fileExtension: ".xls",
            filename: "export-buttons-table",
            mimeType: "application/vnd.ms-excel"
        },
        ...
    }
};
*/
```

#### [`getFileSize`](https://tableexport.v3.travismclarke.com/examples/exportButtons.html)

```javascript
var tableId = "export-buttons-table";
var XLS = table.CONSTANTS.FORMAT.XLS;

/* get export data (see `getExportData` above) */
var exportDataXLS = table.getExportData()[tableId][XLS];

/* get file size (bytes) */
var bytesXLS = table.getFileSize(exportDataXLS.data, exportDataXLS.fileExtension);

/**********************************
 ** bytesXLS (file size in bytes)
 **********************************
352
*/
```

#### [`update`](https://tableexport.v3.travismclarke.com/examples/update_reset_remove.html)

```javascript
/* update */
table.update({
  filename: "newFile" // pass in a new set of properties
});
```

#### [`reset`](https://tableexport.v3.travismclarke.com/examples/update_reset_remove.html)

```javascript
/* reset */
table.reset(); // useful for a dynamically altered table
```

#### [`remove`](https://tableexport.v3.travismclarke.com/examples/update_reset_remove.html)

```javascript
/* remove */
table.remove(); // removes caption and buttons
```

### Settings

Below are some of the popular configurable settings to customize the functionality of the library.

#### [`ignoreCSS`](https://tableexport.v3.travismclarke.com/examples/ignore-row-cols-cells.html)

```javascript
/**
 * CSS selector or selector[] to exclude/remove cells (<td> or <th>) from the exported file(s).
 * @type {selector|selector[]}
 * @memberof TableExport.prototype
 */

// selector
TableExport.prototype.ignoreCSS = ".tableexport-ignore";

// selector[]
TableExport.prototype.ignoreCSS = [".tableexport-ignore", ".other-ignore-class"];

// OR using jQuery

// selector
$.fn.tableExport.ignoreCSS = ".tableexport-ignore";

// selector[]
$.fn.tableExport.ignoreCSS = [".tableexport-ignore", ".other-ignore-class"];
```

#### [`emptyCSS`](https://tableexport.v3.travismclarke.com/examples/ignore-row-cols-cells.html)

```javascript
/**
 * CSS selector or selector[] to replace cells (<td> or <th>) with an empty string in the exported file(s).
 * @type {selector|selector[]}
 * @memberof TableExport.prototype
 */

// selector
TableExport.prototype.emptyCSS = ".tableexport-empty";

// selector[]
TableExport.prototype.emptyCSS = [".tableexport-empty", ".other-empty-class"];

// OR using jQuery

// selector
$.fn.tableExport.emptyCSS = ".tableexport-empty";

// selector[]
$.fn.tableExport.emptyCSS = [".tableexport-empty", ".other-empty-class"];
```

```javascript
/* default charset encoding (UTF-8) */
TableExport.prototype.charset = "charset=utf-8";

/* default `filename` property if "id" attribute is unset */
TableExport.prototype.defaultFilename = "myDownload";

/* default class to style buttons when not using Bootstrap or the built-in export buttons, i.e. when (`bootstrap: false` & `exportButtons: true`)  */
TableExport.prototype.defaultButton = "button-default";

/* Bootstrap classes used to style and position the export button, i.e. when (`bootstrap: true` & `exportButtons: true`) */
TableExport.prototype.bootstrapConfig = ["btn", "btn-default", "btn-toolbar"];

/* row delimeter used in all filetypes */
TableExport.prototype.rowDel = "\r\n";
```

```javascript
/**
 * Format-specific configuration (default class, content, mimeType, etc.)
 * @memberof TableExport.prototype
 */
formatConfig: {
    /**
     * XLSX (Open XML spreadsheet) file extension configuration
     * @memberof TableExport.prototype
     */
    xlsx: {
        defaultClass: 'xlsx',
        buttonContent: 'Export to xlsx',
        mimeType: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',

        fileExtension: '.xlsm'
    },
    xlsb: {
        defaultClass: 'xlsb',
        buttonContent: 'Export to xlsb',
        mimeType: 'application/vnd.ms-excel.sheet.binary.macroEnabled.main',
        fileExtension: '.xlsb'
    },
    /**

     */
    xls: {
        defaultClass: 'xls',
        buttonContent: 'Export to xls',

     */
    txt: {
        defaultClass: 'txt',
        buttonContent: 'Export to txt',
        separator: '  ',
        mimeType: 'text/plain',
        fileExtension: '.txt',
        enforceStrictRFC4180: true
    }
},

//////////////////////////////////////////
// Configuration override example
//////////////////////////////////////////

/* Change the CSV (Comma Separated Values) `mimeType` to "application/csv" */
TableExport.prototype.formatConfig.xlsx.mimeType = "application/csv"
```

### CSS

[TableExport](https://tableexport.travismclarke.com) packages with customized [Bootstrap](http://getbootstrap.com/getting-started/#download) CSS stylesheets to deliver enhanced table and button styling. These styles can be *enabled* by initializing with the `bootstrap` property set to `true`.

```javascript
TableExport(document.getElementsByTagName("table"), {
  bootstrap: true
});
```

When used alongside Bootstrap, there are four custom classes **`.xlsx`, `.xls`, `.csv`, `.txt`** providing button styling for each of the exportable filetypes.

### Going Forward

#### TODOs

* [x] Update JSDocs and TypScript definition file.
* [x] Fix bug with **CSV** and **TXT** `ignoreRows` and `ignoreCols` (rows/cols rendered as empty strings rather than being *removed*).
* [x] Reimplement and test the `update`, `reset`, and `remove` **TableExport** prototype properties without requiring jQuery.
* [x] Make jQuery as *peer dependency* and ensure proper **TableExport** rendering in browser, AMD, and CommonJS environments.
* [x] Force jQuery to be an optionally loaded module.
* [x] Use the enhanced [SheetJS](https://github.com/SheetJS/js-xlsx#supported-output-formats) `xls`, `csv`, and `txt` formats (exposed via `enforceStrictRFC4180` prototype property).
* [x] Allow `ignoreCSS` and `emptyCSS` to work with any `selector|selector[]` instead of solely a single CSS class.
* [x] Ensure (via testing) full consistency and backwards-compatibility for jQuery.
* [ ] Add **Export as PDF** support.
