I want to write text into the bit of the table that is above the row headers and to the left of the column headers to provide a header to the row headers.

In the example you gave the two columns have a header each, the two rows have a header each. That’s 8 cells occupied. I want to write something into the ninth cell in the top-left.

Thanks Greg,

What is the column number for the row headers?

    The row headers have their own context just like the column headers: CONTEXT_ROW_HEADER

    When you receive CONTEXT_ROW_HEADER, the ROW value will have the row number so you can draw
    the different headings for each row.

    If you have a 2x2 table, you'll get:

        > Two callbacks for the two column headings, each will have CONTEXT_COL_HEADER set, and COL will have the column#.
        > Two callbacks for the two row headings, each will have CONTEXT_ROW_HEADER set, and ROW will have the row#.
        > You'll also get four CONTEXT_CELL calls for each of the 4 cells, where ROW and COL will have the appropriate values for each cell

    Please look at the draw_cell() function in table-simple.cxx, it shows how to draw both row and column headers
    in addition to the cells; note the comments:

  void draw_cell(TableContext context, int ROW=0, int COL=0, int X=0, int Y=0, int W=0, int H=0) {
    static char s[40];
    switch ( context ) {
      case CONTEXT_STARTPAGE:                   // before page is drawn..
        fl_font(FL_HELVETICA, 16);              // set the font for our drawing operations
        return;
      case CONTEXT_COL_HEADER:                  // Draw column headers
        sprintf(s,"%c",'A'+COL);                // "A", "B", "C", etc.
        DrawHeader(s,X,Y,W,H);
        return;
      case CONTEXT_ROW_HEADER:                  // Draw row headers
        sprintf(s,"%03d:",ROW);                 // "001:", "002:", etc
        DrawHeader(s,X,Y,W,H);
        return;
      case CONTEXT_CELL:                        // Draw data in cells
        sprintf(s,"%d",data[ROW][COL]);
        DrawData(s,X,Y,W,H);
        return;
      default:
        return;
