@bocciaman Here's an example (with the descriptions blurred out).
These are six columns of data copied from Excel (Shortcut, Description, Shortcut, Description, Shortcut, Description) and pasted directly into the Table Generator, with the resulting html pasted into the Custom HTML Prompt. You'll see the Table Generator Tool even has styling options, and you can add your own.
Take a look at Fancy Mac-Like HTML Prompts Library and Custom HTML Prompt with Dynamic Size and Position for additional tweaks, like specifying and saving the size/position of window.
