If the table is saved as a variable, rather than saving a figure that shows the table, save the table itself to a text file. You can do that using writetable().
There are several benefits to saving the table to a text file rather than to a figure. The text file is readable if you ever need to read the table back into matlab. A figure will pixelate the text since the text is converted to an image.
If you'd rather save the figure to pdf, to rotate it, use orient().
