Question

This is my code which take attributes in the selected block and aprint its table in the dwg file.

But the problem is that my heading is attribute.tag and its content is attribute.textstring and in my table the heading is not printed instead the record start from the beginning. Please suggest me the solution for the same.

   namespace TableCreation
    {
    public class Commands
    {
    // 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.SetAlignment(row, col, cellAlign);
        tb.SetTextHeight(row, col, textHeight);
        tb.SetTextString(row, col, value);
    }

This is due to the current table style (db.Tablestyle) in which the first row is a 'title' row (merged cells). You can use this first row to display the block name, use the second row for the headers and start filling the values in the third one.

    // 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;
    }
