puzzled by draw grid size

Hello, I have a simple table drawing thing. (Example is simplified but still displays the problem) REBOL [ Title: "A simple table with a colored header" ] tablesize: 4x6 ; columns x rows cellsize: 100x20 table: [ box linen cellsize * tablesize effect [ draw [ fill-pen mint box 0x0 to-pair reduce [ first cellsize * tablesize second cellsize ] ] grid cellsize; Expecting this to draw the grid around cells ] ] view layout table But the grid is drawn in some funny resolution I haven't specified (say something around 7x7). I tried moving the grid command around, but to no avail. Putting a literal 100x20 works, but I don't want to live with that as it would break the idea of being able to reuse it for different table and cell sizes. What am I doing wrong? Regards, Maksa

I guess it is because when the grid definition is being parsed by layout, it is thinks that your variable is some noise and ignores it. Maybe composing the grid effect outside of the layout would get you out of it. (Example is simplified but still shows a solution) tablesize: 4x6 ; columns x rows cellsize: 100x20 box-effect: compose [grid (cellsize)] table: [box linen cellsize * tablesize effect box-effect] view layout table

Hi Maksa, If you compose your effect block, and put parens around cellsize so it gets composed, you should be good to go. tablesize: 4x6 ; columns x rows cellsize: 100x20 table: [ box linen cellsize * tablesize effect compose [ draw [ fill-pen mint box 0x0 to-pair reduce [ first cellsize * tablesize second cellsize ] ] grid (cellsize); Expecting this to draw the grid around cells ] ] view layout table --Gregg
