/* Loop through all table rows (except the
first, which contains table headers): */

/* Get the two elements you want to compare,
one from current row and one from the next: */

// If so, mark as a switch and break the loop:
shouldSwitch = true;
break;

/* If a switch has been marked, make the switch
and mark that a switch has been done: */
