In the shown example, it’s the place to the left of where it says “Date” and above the place where it has “2925”. I would like to write into there.

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;
