原来在dataGridView的编辑列中有个属性DataPropertyName,在这里设置字段名称即可显示,查询结果的字段,全部添加上列后,就不会自动产生列了 //【没有测试】

在编辑列中, HeaderText 姓名 是显示的字段

Data     DataPropertyName  姓名  -- 这是对应的数据库查询出数据的列

Design  (Name)  dgv姓名  - -这是 获取编辑框的内容

           //隐藏某列
dgv.Columns["产品ID"].Visible = false;
dgv.Columns["别名"].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;//设置某列 自动列宽             dgv.Columns["别名"].SortMode = DataGridViewColumnSortMode.Programmatic; //自定义排序    dgv.Sort(dgv.Columns[nColumnIndex], System.ComponentModel.ListSortDirection.Descending); //设置某列排序 设置显示格式 百分比显示

//dgv.Columns["A"].DefaultCellStyle.Format = "P"; //以百分号显示 "0\\%";

dgv.Columns["A"].DefaultCellStyle.Format = "0.00\\%"; //以百分号显示 "0\\%";
