var row
Count
= $('#myTable tr').length;
var rowCount = $('#myTable >tbody >tr').length;
$("#myTable").attr('rows').length;
var rowCount = $('table#myTable:last').index() + 1;
//Helper function that gets a count of all the rows <TR> in a table body <TBODY>
$.fn.rowCount = function() {
return $('tr', $(this).find('tbody')).length;
};
// USAGE:
var rowCount = $('#productTypesTable').rowCount();
alert(jQuery("#jtkList").find("table").eq(0).find("tr").length);
