Here's an all-too-common approach to creating forms in Microsoft Word.
Create a heading. You type some underscores.
Aside from looking messy, with ragged lines on the right, you can only print this form out and fill it in by hand.
Well, let's try filling it out on the computer.
Oops! Probably _not_ what was intended.
Well then there's the right way to do it.
We create a table. At the bottom of each fillable cell, we put a border...
...and we put a form field inside for you to type your text.
Lots of text to enter? No problem. The row height expands to hold the text.
You can tab through each field without affecting the headings...
...and you can still print it out and fill it in by hand, if that's what you still want.
Now _that's_ how you improve Office productivity!
