Re: how to control the pixel sizes of a Grid?

Hi Andreas,

thank you!

I found out something:

I thought I could get a solution by inserting images of the correct
pixel size into each cell.

So I created transparent images with the exact pixel sizes:
50x50 for the inner cells, 50x10 for the horizontal borders, 10x50 vor
the vertical borders.

As a result, I found out that there is always some vertical space
between the images, one or some pixels. I also found out, that the
pixel size of the whole grid has changed after inserting the images,
so that it is not a square anymore.

I inserted some visible pixels into the transparent images, and I
verified that there is vertical space between the images.

(I set cellspacing and cellpadding to 0)

How can I get the grid to show its cells without any space?

Thanks
Magnus
