What you can do with a table on a slide

My first suggestion would be to take it off...
if your table has more than 4 columns and rows and more than 15 words, I would really suggest this.
Split up the table. There are probably multiple ideas comprised in there. Give each idea its own slide and explain or visualize it. You can then use a simplified table to sum up your findings with one or two words per columns.
And then use a powerful feature build into most software packages: Building.
Build columns or rows one by one. Maybe even cell by cell.
The audience won't be overwhelmed with information and it should be easier to grasp.
