This is a really great question. One thing you can do is measure the height and width of the fonts in System.Drawing.Text and create a sort of pre-renderer in code to figure out if the text will cause the table to flow off-screen. There would be a bit to keep track of, like at what width will the fonts wrap and create a new line and then space between the lines and the margin of the cells. It would be a running total to keep track of the table height by the total number of lines it could contain with your font and it's size and your text plugged-in - and still stay within the bounds of the slide canvas. But once you have all of this, it should give you very good insight into whether or not you need a new slide.
