Insert new row in Table

I have a problem where the :eq() does not accept the counter, n, to insert values to a new column to the table in the HTML.

$(document).ready(function() { var $tablerow = $('table.table').find('tr'); count = 0; $tablerow.each(function(index, value){ count += 1; var $listitem = $(this); n = parseInt($listitem.index()); var $newRow = $("<td>" + n + "</td>"); $("table.table tr:eq(n)").append($newRow); }); });


<table class="table"> <tr><td>First row</td></tr> <tr><td>second row</td></tr> <tr><td>third row</td></tr> <tr><td>fourth row</td></tr> <tr><td>fifth row</td></tr> <tr><td>sixth row</td></tr> <tr><td>seventh row</td></tr> <tr><td>eighth row</td></tr> </table>


Written as-is, you're doing nothing more than writing a literal character, 'n', into .eq() method. Try this:

$("table.table tr:eq(" + n + ")").append($newRow);


May be try using it like previous line where you used qoutes $("table.table tr:eq(" + n + ")").append($newRow);


No need to index this inside $.each since as your arguments show the first one is index.

$(document).ready(function() { var $tablerow = $('table.table tr'); $tablerow.each(function(index,element){ /* "this" is current row*/ $(this).append("<td>" + index+1 + "</td>" ) }); });



var $newRow = $("<td>" + n + "</td>"); $("table.table tr:eq(n)").append($newRow);`


var $newRow = $("<td>" + (n+1) + "</td>"); $("table.table tr:eq(" + n + ")").append($newRow);

This will work
