加上参数：nowrap: false,即可。 如下代码：$("#userList").datagrid({ width: 'auto', height: 'auto', fitColumns:true, nowrap: false, collapsible: true, singleSelect: true, rownumbers: true, url:"test/overload!getList.action", columns: [[ {"field":"id","title":"","width":120,"align":"center", "hidden":true}, {"field":"name","title":"姓名","width":300,"align":"center"}, {"field":"age","title":"年龄","width":100,"align":"center"}, {"field":"unit","title":"单位","width":300,"align":"center"} ]] });
