Hi Team,

i have a table, with first column name "Assign" having check box and last column name "Assigned to", i need a jQuery logic to check last column value in each row and if the value is empty make the check box checked in the first column.

What I have tried:

$("table[role='grid'] tr:not(:first)").each(function () {
var valueOfCell = $(this).find('td:last-child').text();
alert(valueOfCell);

//check if the value is empty
if (valueOfCell == ''){
// how do i get the first column ...
}
});
