/* 列表头合并。
索引从0开始,包含隐藏列,注意jqgrid的自动序号列也是一列。
使用方法:
$("#jqGridId").tuiJqgridColSpan({
cols: [
{ indexes: "3, 4", title: "合并后的大标题" },
{ indexes: "6, 7", title: "合并后的大标题" },
{ indexes: "11, 12, 13", title: "合并后的大标题" }
]
});
注意事项:
1.没有被合并的rowSpan=2,即两行。列的拖拉有BUG,不能和jqgrid的显示层位置同步;
2.jqgrid的table表头必须有aria-labelledby='gbox_tableid' 这样的属性;
3.只适用于jqgrid;
