There are a couple ways. One is to make sure that your PPT slide size
and the PDF page size you're printing to match, then choose Scale to
fit Paper in the print dialog box. This assumes you're printing to a
PDF driver; I'm not sure what options are open to you with the MacOS
PDF feature. If you can't set the size, then make a PDF, open it in
Reader/Acrobat and note the page size; change the PPT size to match and
see if that helps.
If you have Acrobat, you can crop the PDF to remove any white space in
it.

Use the Frame Slides option in the print dialog box when you print.

Don't use a table. Draw a rectangle, set the line color/width to suit
your needs, then set the fill color to None.
