Center a table on the page in Microsoft Word
This should be pretty easy using the Table's properties. Try this:
Select your table, then right click.
On the Table Tab, Text Wrapping, choose Around. This should activate the Positioning option.
Select Positioning, and in the Table Positioning dialog box, set:
Horizontal Position = Center, Relative to Page
Vertical Position = Center, Relative to Page
Move with Text = unchecked
OK out of the dialog boxes and your Table should be centered. And it should stay centered regardless
of changes to the Table (e.g. adding rows) or changes to surrounding text (including the extra, "silly line".
You shouldn't even have to modify the Page Layout Property, this solution addresses the Table's location
regardless of the Page's properties, so any text you may want to add could still be top justified.
