# [pdftex] table caption, vertical spacing

I know that I'm using an old version of pdfTeX, but before I go
through all the work of upgrading, I'd like someone to please verify
an issue I'm seeing.  In fact, since I'm very new to (La)TeX, this
may be expected behavior.

I'm making a table and the vertical spacing between the caption and
the top border of the table is changing with the width or number of
columns in the table.  I've copied my pdfTeX code, below.  As
written, there's a fairly tall space between the table and it's
caption; however, remove the "&" from "Closest Approach (GMT) & " in
the first row and the caption will shift down to be just above border.

Is this supposed to happen?  Does it happen with the latest version of pdfTeX?

Thanks,

Troy.
