<p>This is the first in a series of tutorials that will cover Excel in depth.</p>
<p>This is also then first Screenbook in a five book set that walks through some of Excel's most interesting features.</p>
<p>It is customary to start out with the simplest functions and work up to more difficult ones, but let's try starting by walking through a project that shows just how powerful Excel can be. </p>
<p>OK, things are starting to clear up a bit. We can see that we have a table of data in columns A - F, and some other information in columns G-I. Lets make the tables easier to see by formatting the column headers (the titles of the columns).</p>
<p>First, let's do the table in columns A-F. Select the column headers by first clicking on column A1 and then dragging the mouse over to column F1. The cells become highlighted to show that they are selected.</p>
