Tables in landscape moving left

Hi,

I am creating a Table flowable in Reportlab using a SimpleDocTemplate in
landscape mode. I am trying to make the columns of the Table wide enough
for the labels, and every time I make it a little wider, the table moves to
the left. I am attaching a screenshot. I need to make several more of the
table columns wider to fit the data and to make the table better cover the
page.

I noticed that if I increase the leftMargin parameter for the template, it
will push the table to the right, but there's got to be a better way, right?

Thanks!
