General ⇒ Vertical align within a cell in a tabular environment

[pittopitto]

Hello guys,

I have a question for you... Hope it's not too hard.

I have created a {table} environment and inside of it a {tabular} environment.
There are three columns and 10 rows. In the first column I've put graphical schemes and in the other two columns the predictions and observations of my analysis, that are NOT graphical, but equations.

Now, because of the graphics in the first column, the rows are actually taller than normal which is normal, but the equations in the second and third column are vertically aligned at the bottom making the table looking VERY ugly.
I've been searching, unsuccessfully, over the net on how could I center align the content of each cell in the table BOTH vertically and horizontally. Yeah, I want the equations at the center of the cells. Any idea???

Please help!

Many Thanks

Gianluca

It's not very easy to help without having any idea of the code you used...

Load the array package and try the m descriptor. Look at the manual here. Just a small example:

Code: Select all

\begin{tabular}{m{3cm}m{3cm}}
   \rule{2cm}{5cm} & $E=mc^2$ \\
   \rule{2cm}{5cm} & $E=mc^2$ \\
   \rule{2cm}{5cm} & $E=mc^2$ 
\end{tabular}

The \rule commands replace the \includegraphics ones in your code.

Hi,

I have a problem similar to pittopitto's and tried the array package but it didn't help me.

I have a table with two narrow left-aligned columns, a column with a formula which should be aligned in the middle of the cell (horizontally and vertically) and a fourth column with a (long) paragraph of text.

The column with the formula should resize to the with of the widest formula. The last column with the paragraph determines the height of each row depending on the length of the text.

First I defined the table this way which aligns the formula at the top
\begin{tabular}{|l|l|c|p{40mm}|}

Juanjo's example works in his example but the following aligns my formulae at the top-left...
\begin{tabular}{|l|l|m{60mm}|p{40mm}|}

What am I missing? I've also been searching, the following came closest but didn't solve the issue http://start.it.uts.edu.au/w/doc/LaTeX/tabular.html

Help! :'(

Your third column with formulae (math formulae, I suppose) should be called with
\begin{tabular}{|l|l|>{\centering $}m{60mm}<{$}|p{40mm}|}
I don't know whether it it will solve your problem, but it is the correct syntax to obtain centered formulae. If it doesn't solve anything, what is your preamble?

What about this other example?

Code: Select all

\begin{tabular}{|l|l|>{$\displaystyle}c<{$}|>{\raggedright}m{40mm}|}
  \hline
  blah & blah & \frac{x^2-1}{x-1}=x+1 & 
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah \tabularnewline
  \hline
  blah & blah &  \frac{x^3-1}{x-1}=x^2+x+1  & 
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah \tabularnewline
  \hline
\end{tabular}

You can replace \tabularnewline by \\ if you remove the \raggedright declaration.
