Dependencies

Required:

FileSaver.js

Optional:

jQuery (1.2.1 or higher)
Bootstrap (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 and TableExport.

xlsx.core.js by SheetJS

Including xlsx.core.js is NOT necessary if installing with Bower or npm

<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 polyfill before the FileSaver.js script.

Blob.js by eligrey (forked by clarketm)

Including Blob.js is NOT necessary if installing with Bower or npm

<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 constructor:

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')
});

Note: to use the xlsx filetype, you must include js-xlsx; reference the Add-Ons section.

Properties

Methods

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"));

`getExportData`

/* 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`

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`

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

`reset`

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

`remove`

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

Settings

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

`ignoreCSS`

/**
 * 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`

/**
 * 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"];

/* 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";

/**
 * Format-specific configuration (default class, content, mimeType, etc.)
 * @memberof TableExport.prototype
 */
formatConfig: {
    /**
     * XLSX (Open XML spreadsheet) file extension configuration
     * @memberof TableExport.prototype

        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 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.

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 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.
