Graphics, Figures & Tables ⇒ Table placement in Beamer and pdf output

[venik]

Two questions:
1) I created a table in Beamer, but I cannot center it. It ignores \centering , \begin{center}..\end{center} and even hspace{-.2in} does not work. It seems that Beamer uses a rather coarse grid, since positioning the table horizontally using hspace does not work and then overshoots the mark, leaving part of the table invisible.

2) I did all this in Lyx (1.6.7, Linux 64 bit), but when I exported it to Latex and ran it again (to discover whether the problem is with Lyx or with Latex/Beamer), I found that figures that looked fine under Lyx were shifted vertically when I compiled the .tex file into pdf. Why is there a difference between what Lyx (which is only a GUI front to Latex) produces and what Latex outputs?

Hi venik,

perhaps post a minimal working example showing the problem. Your description does not tell which tabular environment do you use and if you use a (floating) table environment.

Since I am not sure how to post Latex files, I shall paste it here. As you can see, the Latex was exported from Lyx, and the table is not floating (no sense in floating graphics in a Beamer presentation).
Thanks for your help
