Fix First Column of a Bootstrap Table

I followed @koala_dev's code in this post to try to lock the first column s my table scrolls horizontally. The code unfortunately has no effect on my table. I was wondering if anyone could give me some pointers on what I have done wrong as I am new to programming.

This is my table: http://jsfiddle.net/mademoiselletse/bypbqboe/59/

This is the code I inserted in JS (line 121-133):

$(function() {
    var $tableClass = $('.table');
    // Make a clone of our table
    var $fixedColumn = $tableClass.clone().insertBefore($tableClass).addClass('fixed-column');

    // Remove everything except for first column
    $fixedColumn.find('th:not(:first-child),td:not(:first-child)').remove();

    // Match the height of the rows to that of the original table's
    $fixedColumn.find('tr').each(function(i, elem) {
      $(this).height($tableClass.find('tr:eq(' + i + ')').height());
    });
});

This is the CSS properties (line 36-47) I have inserted:

.table-responsive > .fixed-column {
   position: absolute;
   display: inline-block;
   width: auto;
   border-right: 1px solid #ddd;
}

@media(min-width:768px) {
    .table-responsive>.fixed-column {
        display: none;
    }
}

The only thing I deviated from the demo code was that I defined $('.table') as $tableClass instead of $table since I have previously defined var $table as $('#table') . Your help will be much appreciated!

Ok.. Remove all your js code and you can do this with some CSS tricks as below:

DEMO

CSS

.table > thead:first-child > tr:first-child > th:first-child {
    position: absolute;
    display: inline-block;
    background-color: red;
    height: 100%;
}

.table > tbody > tr > td:first-child {
    position: absolute;
    display: inline-block;
    background-color: red;
    height: 100%;
}

.table > thead:first-child > tr:first-child > th:nth-child(2) {
    padding-left: 40px;
}

.table > tbody > tr > td:nth-child(2) {
    padding-left: 50px !important;
}

$('#table') means your finding element by id table.

$('.table') means your finding elements by class table.

These are the CSS selectors you used in css.

In your case, your table had id table so you can select that table using $('#table').

And you don't have any html elements using class table, so you'll get nothing when you select using $('.table').

As I tested @Guruprasad Rao 's answer , it has a bug if you display th, td are : "inline-block" instead of default display :"table-cell" width of column 1 in header and width of column 1 in tbody are not same width
