JS：

/**
* EasyUI DataGrid根据字段动态合并单元格
* @param fldList 要合并table的id
* @param fldList 要合并的列,用逗号分隔(例如："name,department,office");
*/
function MergeCells(tableID, fldList) {
var Arr = fldList.split(",");
var dg = $('#' + tableID);
var fldName;
var RowCount = dg.datagrid("getRows").length;
var span;
var PerValue = "";
var CurValue = "";
var length = Arr.length - 1;
for (i = length; i >= 0; i--) {
fldName = Arr[i];
PerValue = "";
span = 1;
for (row = 0; row <= RowCount; row++) {
if (row == RowCount) {
CurValue = "";
}
else {
CurValue = dg.datagrid("getRows")[row][fldName];
}
if (PerValue == CurValue) {
span += 1;
}
else {
var index = row - span;
dg.datagrid('mergeCells', {
index: index,
field: fldName,
rowspan: span,
colspan: null
});
span = 1;
PerValue = CurValue;
}
}
}
}
