jsTable is a mootools control designed to make it easy to add serializable data tables to the page with javascript.



See this page for a demo of jsTable in action.

How to Use

(This is only a summary. Please see the documentation for a method by method description of usage)

If we have a div object in the html that looks like this:

<div id='new-table'></div>

It can be turned into a jsTable by constructing the object and passing the element as a parameter.

var jst = new jsTable('new-table');

Then we add some columns to the table:

// usage: addColumn(column_name, column_description);
jst.addColumn('filename', 'File Name');
jst.addColumn('size'); // if the description is not given, the column name is used instead

Now data can be added to the table. Elements can be added, as well simple strings and html.

// usage: addRow(column1, column2, ...)
jst.addRow('test.txt', '12kb');

You can get and set the contents of the cells using the setCell, getCell functions

var contents = jst.getCell(row_index, column_name);
jst.setCell(row_index, column_name, contents);


Use css to style the table, and the hide or show certain columns. You could hide the header by simply doing the following.

#new-table thead {
    display: none;

The column names are applied to the table cells as css classes and can be used also. The class names are prefixed with 'jst-'

/* hide the 'size' column */
#new-table td.jst-size, #new-table th.jst-size  {
    display: none;

These classes can also be used to set borders, font sizes, padding etc.


You can serialize the table to a javascript object, or to a json string using the methods toJson and toData respectively.

// set up a table with two columns
jst = addTable('new-table);

// add some rows to the table
jst.addRow(10, 20);
jst.addRow(30, 40);

You would get html that looks a bit like this:

    <tr><td class='jst-n1'>10</td> <td class='jst-n2'>20</td></tr>
    <tr><td class='jst-n1'>30</td> <td class='jst-n2'>40</td></tr>

Using the toJson method would serialize it this:

// jst.toJson();
    {'n1':10, 'n2':20},
    {'n1':30, 'n2':40}

You can also serialize just a single column:

//result from jst.toJson('n1');
[10, 30]

Use Inheritence for Custom Tables

If the same table will be used in multiple places on the page, it can be useful to create a new Class for it, inheriting from jsTable, rather than doing the addColumn setup everytime.

Such a class would look something like this:

var FileTable = new Class({
    Extends: jsTable,
    initialize: function(element, options) {
        this.parent(element, options);
        this.addColumn('filename', 'File Name');
