General ⇒ help with tabular columns please

[masterkajo]

I am trying to to a very simple table that accomplishes two things:
1. set the width of both columns to 4cm (to get appr. 8cm table)
2. center both columns' input

\begin{tabular}[H]{ c | c }
nicht gewichtet & statistisch gewichtet \\ \hline \\
$\frac{\Delta x_c}{x_c} = 0,00343$ & $\frac{\Delta x_c}{x_c} = 0,00543$ \\
$\frac{\Delta w}{w} = 0,03769$ & $\frac{\Delta w}{w} = 0,05194$ \\
$\frac{\Delta A}{A} = 0,03264$ & $\frac{\Delta A}{A} = 0,05410$ \\
\end{tabular}

{c | c} centers the fractions however the columns have different width, which I don't want.
{p{4cm} | p{4cm}} sets both columns' width to 4cm but doesn't center the input

I'd really appreciate your help as this paper is due to monday.

Hi,

you could use p-columns and \centering inside the table cells.
Additionally you may use the aligned environment of amsmath, to align the equal signs:

Code: Select all

\begin{tabular}[H]{p{4cm}|p{4cm}}
nicht gewichtet & statistisch gewichtet \\ \hline \\
\centering$\begin{aligned}
  \tfrac{\Delta x_c}{x_c} &= 0,00343 \\
  \tfrac{\Delta w}{w} &= 0,03769 \\
  \tfrac{\Delta A}{A} &= 0,03264
\end{aligned}$ & 
\centering$\begin{aligned}
  \tfrac{\Delta x_c}{x_c} &= 0,00543 \\
  \tfrac{\Delta w}{w} &= 0,05194 \\
  \tfrac{\Delta A}{A} &= 0,05410
\end{aligned}$
\end{tabular}

Of course you can use \centering inside the first row too. And there may be other ways than that example above.

Thank very much... I still got some minor problems but I managed to accomplish what I want after a little weaking.

One question though, why do you use the command \tfrac{}{}? When I try it, I do not get a fraction but rather a multiplication. Anyway thanks again!

Hi,

I used \tfrac because it gives the fraction like {\textstyle\frac ... } (actually defined as \genfrac{}{}{}1) , see amsmath user's manual. It should work if you are using amsmath.
