easyui内容合并单元格

在easyui的方法中调用 onLoadSuccess: function () {
autoMergeCells('tableDataGrid', ["分类一", "分类一数量", "分类一占比"],"分类一");
},

//自动合并单元格 

//三个参数分别为：表格id，要合并字段的数组，判断字段（不一样则不合并）即以哪一类为准

function autoMergeCells(table_id, field_arr, judge) {
var rows = $("#" + table_id).datagrid("getRows");
if (NULL(field_arr) || NULL(rows)) {
return;
}
for (var i = 1; i < rows.length; i++) {
for (var k = 0; k < field_arr.length; k++) {
var field = field_arr[k]; //要排序的字段
if (rows[i][field] == rows[i - 1][field]) { //相邻的上下两行
if (NOTNULL(judge)) {
if (rows[i][judge] != rows[i - 1][judge]) {
break;
}
}
var rowspan = 2;
for (var j = 2; i - j >= 0; j++) { //判断上下多行内容一样
if (rows[i][field] != rows[i - j][field]) {
break;
} else {
if (NOTNULL(judge)) {
if (rows[i][judge] != rows[i - j][judge]) {
break;
}
}
rowspan = j + 1;
}
}
$("#" + table_id).datagrid('mergeCells', { //合并
index: i - rowspan + 1,
field: field,
rowspan: rowspan
});
}
}
}
}

function NOTNULL(obj) {
if (typeof (obj) == "undefined" || obj === "" || obj == null || obj == "null") {
return false;
}
return true;
}
function NULL(obj) {
if (typeof (obj) == "undefined" || obj === "" || obj == null || obj == "null") {
