Simple jQuery code snippet to remove an entire table column based on the column number. It also removes the table row heading associated with the removed column.

//remove the 1st column
$('#table').find('td,th').first().remove();
//remove the 1st column
$('table tr').find('td:eq(1),th:eq(1)').remove();
//remove the 2nd column
$('table tr').find('td:eq(1),th:eq(1)').remove();
//remove the nth column
$('table tr').find('td:eq(n),th:eq(n)').remove();
