Set checkbox value in all checkbox of grid

How to set all checkbox value from column header checkbox, I am having following function on click for column header checkbox having argument column header name & checkbox object.

function handleClick(cb, sName) {
  var table= $("#GridName");
  $('td input:checkbox',table).prop('checked',cb.checked);
