                             1.添加引用:DBClient2.置DBGridEh控件属性:  设置dghAutoSortMarking属性为true  设置希望排序的Column的TitleButton属性为true
3.//表格排序过程
  procedure OrderGrid(dataSet:TClientDataset;orderField:string);
  var
    i:integer;
  begin
    if dataSet.IndexFieldNames'' then
    begin
      i:=TClientDataSet(DataSet).IndexDefs.IndexOf('i'+orderField);
      if i=-1 then
      begin
        with Dataset.IndexDefs.AddIndexDef do
        begin
          Name:='i'+orderField;
          Fields:=orderField;
          DescFields:=orderField;
        end;
      end;
      dataSet.IndexFieldNames:='';
      dataSet.IndexName:='i'+orderField;
    end
    else
    begin
      dataSet.IndexName:='';
      dataSet.IndexFieldNames:=orderfield;
    end;
  end;
4.在DBGridEh的OnTitleClick事件中调用OrderGrid(DM.ClientDataset,Column.FieldName);
