Layout Tables

You need to remember that screen readers will read information cell-by-cell from left to right, top to bottom.

So the information in this table is read by a screen reader as: "1,2,3,4,5,..."

We this table to contain text...

This	is	a
nice	table.

It would read: "This is a nice table."

Now, if you were using this as a way to layout information about your real estate business and you wanted to say:

"Housing Sales are Going Up, Up Up!"

and you formatted it in a "clever" way to depict the idea of Up, Up Up going, up, up up...you might layout the table like this:

Notice I left made the borders = 0

This Layout would be read by a screen readers:

"House Up! Sales Up are Going Up"

Which doesn't make all that much sense.
