This image shows a draft of a business card, with lines drawn on it to indicate how rows, columns and spans might be drawn.

A horizontal magenta line in the middle of the card indicates that there are two grids. In the first grid, one horizontal green line and one vertical red line indicate that there are 2 rows and 2 columns.

In the second grid, one horizontal green line and two vertical red lines indicate there are 2 rows and 3 columns. The last column has a yellow cross on it to indicate that those cells should be merged with a row span to hold an image.
