扩展方法： $.extend($.fn.datagrid.methods, {    autoMergeCells: function(jq, fields) {        return jq.each(function() { var target = $(this); if (!fields) { fields = target.datagrid("getColumnFields"); } var rows = target.datagrid("getRows"); var i = 0, j = 0, temp = {}; for (i; i < rows.length; i++) { var row = rows[i]; j = 0; for (j; j < fields.length; j++) { var field = fields[j]; var tf = temp[field]; if (!tf) { tf = temp[field] = {}; tf[row[field]] = [i]; } else { var tfv = tf[row[field]]; if (tfv) { tfv.push(i); } else { tfv = tf[row[field]] = [i]; } } } } $.each(temp, function(field, colunm) { $.each(colunm, function() { var group = this; if (group.length > 1) { var before, after, megerIndex = group[0]; for (var i = 0; i < group.length; i++) { before = group[i]; after = group[i + 1]; if (after && (after - before) == 1) { continue; } var rowspan = before - megerIndex + 1; if (rowspan > 1) { target.datagrid('mergeCells', { index: megerIndex, field: field, rowspan: rowspan }); } if (after && (after - before) != 1) { megerIndex = after; } } } }); }); }); } });

使用方法

在datagrid的onLoadSuccess事件里面进行调用，可以实现数据加载完成后，自动合并。也可以手动调用该方法。

$('#dg').datagrid({    url: 'datagrid_data.json',    onLoadSuccess: function(data) { //所有列进行合并操作 //$(this).datagrid("autoMergeCells"); //指定列进行合并操作 $(this).datagrid("autoMergeCells", ['groupId', 'commId']); } });
