Easyui数据表格合并单元格

合并与不合并的数据在同一个表中：

$('#table_id').datagrid({
        title: '标题',
        collapsible: true,
        singleSelect:true,
        nowrap: true,
        loadMsg: "数据加载中......",
        onLoadSuccess: mergeCellsSuccess,

$.ajax({
        url: "XXX.html",
        type: 'GET',
        dataType: 'json',
        contentType: "application/json",
        data: {A1: A1, A2: A2},//条件
        success: function (tabdata) {
            console.log(tabdata)
            $('#table_id').datagrid('loadData', tabdata.list); //将数据绑定到datagrid
 });

/**
 * 合并单元格
 * @param data
 */
function mergeCellsSuccess(data) {
    var cells = ['要合并的字段1', '要合并的字段2','要合并的字段3'];
    var cellcomp='根据某个字段判断该字段是否相同(如：根据要合并的字段1)，相同就合并';
    mergeCells_New("表格di属性",cellcomp,cells);
}

/**
 * @param table_id:datagrid的id
 * @param cellcomp:cellcomp列相同，cellnames合并
 * @param cellnames:合并的列,var cells = ["要合并的字段1", "要合并的字段2"];
 */
function mergeCells_New(table_id, cellcomp, cellnames) {
    var merges = [];
    var rows = $("#" + table_id).datagrid("getRows");
    for (var r = 0; r < rows.length; r++) {
        var row = rows[r];
        var mergeinfo = new Object();
        var nr = row[cellcomp];
        var rowspan = 1;
        for (var r1 = r + 1; r1 < rows.length; r1++) {
            var row1 = rows[r1];
            var nr1 = row1[cellcomp];

                    r = r1 - 1;
                }
                break;
            }
            if (r1 == rows.length - 1) {
                if (rowspan > 1) {
                    merges.push(mergeinfo);
                    r = r1 - 1;
                }
            }
        }
    }
    for (var i = 0; i < cellnames.length; i++) {

        }
    }
}

合并与不合并的数据不在同一个表中
调用：

$('#tableID').datagrid({
	title: '表格标题',
	singleSelect:true,//只能单选
	onLoadSuccess: onLoadSuccess,//调用方法
});

 */

 * @param table_id
 * @param mergeList
 * @param field_arr
 */
