　　$ ( "layui-the Table-the Sort-desc.") CSS ( "border-Top-Color", "# 000");. 
// listen for sorting event 
        table.on ( 'sort (test)' , function (obj) {// NOTE: sort event name is the toolbar, Test lay-filter table is a property of the original container = "a value corresponding to" 
           table.reload ( 'listTable', { 
            initSort: // obj initial ordering records, if it does not , will not mark the state table sorting head. 
            , WHERE: {// request parameters (Note: this parameter can be arbitrarily defined which is not a fixed format below) 
              field: obj.field // sort field 
              , order: obj.type // Sort 
            } 
          }); 
        }); 
    });

Secondly, it is to change the background of sql statement

<choose>
                <when  test="field!=null and order == 'asc'.toString()">
                   order by a.HANDLE_STATUS ASC,a.ALARM_TIME DESC,a.HANDLE_TIME DESC
                </when>
                <otherwise>
                   order by a.HANDLE_STATUS DESC,a.HANDLE_TIME DESC,a.ALARM_TIME DESC
                </otherwise>
         </choose>
