# How can the margins around a table set to 0pt?

I need to put a table inside another table, and would like to set the outside margins of the inner table to 0pt. How can I do this (in particular for tabularx, but hopefully this would be the same for any table environment)?

\begin{tabularx}{1in}{@{}ll@{}}...\end{tabularx}. Why do you need a table inside a table? –  TH. Apr 20 '11 at 15:29
@TH.: Why not? I do this also from time to time to align a normal tabular with other things. –  Martin Scharrer Apr 20 '11 at 15:35
@Martin: It seems like the 1990's HTML version of page layout. –  TH. Apr 20 '11 at 15:47
@TH.: I know, but for simply things it is straight forward. I use the Web 2.0/CSS version of page layout as well (i.e. positioning using TikZ). –  Martin Scharrer Apr 20 '11 at 15:48
@TH.: I am using it for creating a particular form which basically needs a long table over multiple pages with a header and footer which are also in table form. if there is a better way to create such a layout, I am open to it –  txwikinger Apr 20 '11 at 16:14
