Tables are a good way to arrange data. Nice, structured, borders between each cell, etc.
The only question is, how do you get the data into a table format?
You can type from scratch, of course. You can painfully copy and paste.
Or if your data is set up right, with a tab or comma or other item separating the data into columns, you can just convert the text to a table.
Let's say you've got this. The arrows are tabs separating the "columns" of data. (And let's say that it's actually about ten pages long, since this feature is a big timesaver but only if you've got a bunch of data to convert.) The blue is just artistic license.
Select it all.
Choose Table > Convert > Text to Table.
You'll see this window, where you can specify exactly what separates each column of data. It might be a tab, a comma, etc. Also set the options for headings, in the bottom part of the window. The example text here has headings, but yours might not.
If, through some sort of search-and-replace procedure, or for whatever reason, the % or & character separates each column, then you can specify that. As long as it's a keyboard character, you can specify it.
Click OK, and you've got your table.
