在現有表格中添加單行

Question

這是我的代碼，該代碼在所選塊中具有屬性，並將其表打印在dwg文件中。

但是問題是我的標題是attribute.tag，其內容是attribute.textstring ，在我的表中沒有打印標題，而是從頭開始記錄。 請為我建議相同的解決方案。

   namespace TableCreation

    // for the table

    private const double colWidth = 15.0;
    private const double rowHeight = 3.0;
    private const double textHeight = 1.0;

    private const CellAlignment cellAlign =
      CellAlignment.MiddleCenter;

    // Helper function to set text height
    // and alignment of specific cells,
    // as well as inserting the text

這是由於當前表樣式（db.Tablestyle）的原因，其中第一行是“標題”行（合並的單元格）。 您可以使用第一行顯示塊名稱，使用第二行作為標題，然后開始在第三行中填充值。

    // Set up some formatting constants
    // for the table

    private const double colWidth = 15.0;
    private const double rowHeight = 3.0;
    private const double textHeight = 1.0;
    private const CellAlignment cellAlign = CellAlignment.MiddleCenter;

    // Helper function to set text height
    // and alignment of specific cells,
    // as well as inserting the text

    static public void SetCellText(Table tb, int row, int col, string value)
    {
        tb.Cells[row, col].Alignment = cellAlign;
        tb.Cells[row, col].TextHeight = textHeight;
        tb.Cells[row, col].Value = value;
    }
