EasyUI datagrid 标题列和数据列不能对齐的问题处理

最近在做一个Easyui datagrid数据时，发现标题列和数据列不能对齐，网上也找了些办法，都嫌麻烦，经过反复调试，发现field随便赋值就能解决了。代码如下：

 {
                 field: "WriteAnyThing",
                 title: "操作",
                 formatter: function (value, row, index) {
                     var str = "";
                     str += "<a href='javascript:void(0)' uid='" + row.ID + "' class='editLink'>修改</a> &nbsp;&nbsp;"
                     str += "<a href='javascript:void(0)'  uid='" + row.ID + "'  class='deleteLink'>删除</a>"
                     return str;
                 },
              

             }

WriteAnyThing是随便写的。
