Answer 1

This is the answer I found so far for my needs: Link here.

It creates a new command that will make a table inside a table in a more proper way:

\newcommand{\specialcell}[2][c]{%
\begin{tabular}[#1]{@{}c@{}}#2\end{tabular}}

So, if want to do a forced line break inside a cell like here:

\begin{tabular}{|c|c|c|}
\hline
Foo bar & Foo  bar & Foo bar \\
\hline
\end{tabular}

You will end up using a code like this:

Foo bar & \specialcell{Foo\\bar} & Foo bar \\    % vertically centered
Foo bar & \specialcell[t]{Foo\\bar} & Foo bar \\ % aligned with top rule
Foo bar & \specialcell[b]{Foo\\bar} & Foo bar \\ % aligned with bottom rule

Horizontal alignment can be controlled in the declaration of the new command by changing c@ to l@ or r@
