layui框架table表格实现单击行选中checkbox功能

layui.table.on('row(operateEvent)', function (obj) {    var tableDiv;     var index = $(obj.tr.selector).attr('data-index');     var tableBox = $(obj.tr.selector).parents('.layui-table-box');    //存在固定列     if (tableBox.find(".layui-table-fixed.layui-table-fixed-l").length>0) {         tableDiv = tableBox.find(".layui-table-fixed.layui-table-fixed-l");     } else {         tableDiv = tableBox.find(".layui-table-body.layui-table-main");     }    var checkCell = tableDiv.find("tr[data-index=" + index + "]").find("td div.layui-table-cell div.layui-form-radio");            checkCell.on("click", function (e) {                 $(this).off();                 e.stopPropagation();             });            checkCell.find('i').click();     });
