"Many of these limitations and bits of awkwardness are the
direct result of the tools for using tables falling short of true
styles, of the kind available for paragraphs in Writers or drawing
objects in Draw.
"The addition of tables is good news because, like slide shows
in general, tables are all about the visual display of information.
However, before version 3.0, tables required a series of kludges in
Impress. First, you had to create separate text boxes, add borders
and shading to each one. Then, you had to maneuver the text boxes
next to each other, and group them together so that you could
position the table as a whole. If you were wise, you would save the
result as a template so you wouldn't have to repeat this process,
but the initial set up was tedious, and in practice you would have
to tweak your template for individual slide shows."
