Field Initializers
Using the Column Specifications dialog is a good way to setup default data for your columns. It would be great if you could enter simple expressions but hey I can hope! Anyway a neat little trick is that for date columns that you want to initialise to today's date you can include the word Today.

That is not Today() but Today.

NOTE: You can also use:

Empty — A string of length 0
Null — No value
Spaces — All blanks
