你是谷歌呢？看起來非常簡單。

protected void Page_Load(object sender, EventArgs e) 
{   
    if (!IsPostBack) 
    { 
     GridReport.DataSource = <your datatable>; 
     // This is the table I shown in Figure 1.1 

     GridReport.DataBind(); 

     // Your other codes here (if any) 
    } 
} 

protected void btnTransposeReport_Click(object sender, EventArgs e) 
{ 
    DataTable inputTable = <your datatable>; 
    // Table shown in Figure 1.1 

    DataTable transposedTable = GenerateTransposedTable(inputTable); 

    GridReport.DataSource = transposedTable; 
    // Table shown in Figure 1.2 

    GridReport.DataBind(); 
} 

private DataTable GenerateTransposedTable(DataTable inputTable) 
{ 
    DataTable outputTable = new DataTable(); 

    // Add columns by looping rows 

    // Header row's first column is same as in inputTable 
    outputTable.Columns.Add(inputTable.Columns[0].ColumnName.ToString()); 

    // Header row's second column onwards, 'inputTable's first column taken 
    foreach (DataRow inRow in inputTable.Rows) 
    { 
     string newColName = inRow[0].ToString(); 
     outputTable.Columns.Add(newColName); 
    } 

    // Add rows by looping columns   
    for (int rCount = 1; rCount <= inputTable.Columns.Count - 1; rCount++) 
    { 
     DataRow newRow = outputTable.NewRow(); 

     // First column is inputTable's Header row's second column 
     newRow[0] = inputTable.Columns[rCount].ColumnName.ToString(); 
     for (int cCount = 0; cCount <= inputTable.Rows.Count - 1; cCount++) 
     { 
      string colValue = inputTable.Rows[cCount][rCount].ToString(); 
      newRow[cCount + 1] = colValue; 
     } 
     outputTable.Rows.Add(newRow); 
    } 

    return outputTable; 
}
