var start_row ;var row_num = 0;$("#userTable tr").each(function(i){if(i==0){start_row = $(this);}else{if($(this).find("td:eq(1)").text() == start_row.find("td:eq(1)").text()){row_num ++ ;$(this).find("td:eq(0)").hide(); $(this).find("td:eq(1)").hide(); $(this).find("td:eq(8)").hide(); $(this).find("td:eq(9)").hide(); $(this).find("td:eq(10)").hide(); start_row.find("td:eq(0)").attr("rowSpan",row_num); start_row.find("td:eq(1)").attr("rowSpan",row_num); start_row.find("td:eq(8)").attr("rowSpan",row_num); start_row.find("td:eq(9)").attr("rowSpan",row_num); start_row.find("td:eq(10)").attr("rowSpan",row_num); }else{start_row = $(this);row_num ++ ;}}}); ?
