EasyUI datagrid 標題列和數據列不能對齊的問題處理

最近在做一個Easyui datagrid數據時，發現標題列和數據列不能對齊，網上也找了些辦法，都嫌麻煩，經過反復調試，發現field隨便賦值就能解決了。代碼如下：

 {
                 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'>刪除</a>"
                     return str;
                 },
              

             }

WriteAnyThing是隨便寫的。
