FWIW, here's a (compilable) test program similar to your
code snippet I was using to test your issue.
Note the "<--" comment below, as well as the additional
calls to col_width_all() and row_height_all(), which I'd
recommend you use, so that the table knows the width/height
of your child widgets.

void draw_cell(TableContext context, int R=0, int C=0, int X=0, int Y=0, int
W=0, int H=0) {

if ( index >= children() ) break;
find_cell(CONTEXT_TABLE, r, c, X, Y, W, H);
child(index++)->resize(X,Y,W,H);
}
}
init_sizes(); // tell group children resized
return;

return; // fltk handles drawing the widgets

};
int main() {
Fl_Double_Window win(800, 600, "Window");
win.end();
MyTable *t = new MyTable(400, 0, 400, 600);
t->end();
win.add(t);
t->cols(2);
