asp.net中datagrid绑定datatable,为什么显示不出来datatable中的列，附代码，谢谢

[laohuchiren]

DataTable m_Table=new DataTable("pro_v_indentsellcoldetail");
m_Table.Columns.Add("编号");
m_Table.Columns.Add("合计");

MyDataGrid.DataSource=m_Table;
MyDataGrid.DataBind();

为什么datagrid中没有显示列 “编号”，“合计”，谢谢了

private void DispData()

DataTable m_Table= MakeNamesTable();

dr["编号"]="123456";

//dr.AcceptChanges();
m_Table.Rows.Add(dr);
MyDataGrid.DataSource=m_Table;
MyDataGrid.DataBind();
}

private DataTable MakeNamesTable()
{

DataTable namesTable = new DataTable("pro_v_indentsellcoldetail");
// Add three column objects to the table.
DataColumn idColumn = new DataColumn();
idColumn.DataType = System.Type.GetType("System.Int32");

namesTable.Columns.Add(firstCol);
DataColumn SecondCol = new DataColumn();
SecondCol.DataType = System.Type.GetType("System.String");
SecondCol.ColumnName = "合计";
namesTable.Columns.Add(SecondCol);
// Create an array for DataColumn objects.
DataColumn [] keys = new DataColumn [1];
keys[0] = idColumn;
namesTable.PrimaryKey = keys;
// Return the new DataTable.
return namesTable;
