javascript - Fix First Column of a Bootstrap Table

Question

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!

Just add position:sticky to th & td first-child.

th:first-child, td:first-child
{
  position:sticky;
  left:0px;
  background-color:grey;
}
