Facebook shrinks the display of large images to fit their preferred image size.
As a result, the text in tables can seem unreadably tiny.
To see the tables I've posted full size, open the image in its own tab:
Right-click on the image and then selecting "Open Image In New Tab". You may need to do this twice, in order to get to the image by itself.
You can then zoom in on the image by typing CTRL and plus sign ("+") simultaneously.
Zoom out by typing CTRL and minus sign ("-").
