TableExport
The simple, easy-to-implement library to export HTML tables to
xlsx, xls, csv, and txt files.
To use this library, include the FileSaver.js library, and TableExport library before the closing
<body> tag of your HTML document:<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
$ bower install tableexport.js
$ npm install tableexport
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 and TableExport.<script src="xlsx.core.js"></script>
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
To support legacy browsers ( Chrome < 20, Firefox < 13, Opera < 12.10, IE < 10, Safari < 6 ) include the Blob.js polyfill before the FileSaver.js script.
<script src="Blob.js"></script>
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
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./* 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')
});
TableExport supports additional methods (getExportData, update, reset and remove) to control the
TableExport instance after creation./* First, call the `TableExport` constructor and save the return instance to a variable */
var table = TableExport(document.getElementById("export-buttons-table"));
/* 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"
},
...
}
};
*/
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 */
table.update({
filename: "newFile" // pass in a new set of properties
});
/* reset */
table.reset(); // useful for a dynamically altered table
/* remove */
table.remove(); // removes caption and buttons
Below are some of the popular configurable settings to customize the functionality of the library.

TableExport packages with customized Bootstrap CSS stylesheets to deliver enhanced table and button styling. These styles can be enabled by initializing with the
bootstrap property set to true.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. | Chrome | Firefox | IE | Opera | Safari |

A full list of browser support can be found in the FileSaver.js README. Some legacy browsers may require an additional third-party dependency: Blob.js
- Update JSDocs and TypScript definition file.
- Fix bug with CSV and TXT
ignoreRowsandignoreCols(rows/cols rendered as empty strings rather than being removed). - Reimplement and test the
update,reset, andremoveTableExport prototype properties without requiring jQuery. - Make jQuery as peer dependency and ensure proper TableExport rendering in browser, AMD, and CommonJS environments.
- Force jQuery to be an optionally loaded module.
- Use the enhanced SheetJS
xls,csv, andtxtformats (exposed viaenforceStrictRFC4180prototype property). - Allow
ignoreCSSandemptyCSSto work with anyselector|selector[]instead of solely a single CSS class. - Ensure (via testing) full consistency and backwards-compatibility for jQuery.
- Add Export as PDF support.
