Graphics, Figures & Tables ⇒ How To Resize The Height of Cell Aligned Center

[fractal.generator]

Dear all,

The objective is to have a tabular with the following properties

1. the cells are aligned both vertically and horizontally.

2. the cell height can be changed without affecting the content size.

I have tried to solve this problem using rule of zero width as follows

Code: Select all

Code, edit and compile here:

\begin{tabular}{m{0pt}*{3}{|>{\centering\arraybackslash$}m{3cm}<{$}}|}\hline
\rule{0pt}{1cm} &a  & x         & \sin x            \\\hline
\rule{0pt}{1cm} &b  & y  & \cos y                 \\\hline
\rule{0pt}{1cm} &c  & z  & \frac{x}{y}                     \\\hline
\end{tabular}

The first column (as an auxilary column) is inserted to manipulate the cell height.
The formated tabular, unfortunately, shows this column that I actually want to hide.


Is there any trick to solve it?


Thank you in advance.

@localghost,

Thanks very much for replying.

1. booktabs package does not suits my need because I want to change its height manually instead of automatically adjusted.

2. \arraystretch does NOT make the content vertically aligned.
Correction : \arraystretch should be modified using \renewcommand rather than \setlength.

I tried the following trick that suits what I want.
\newcolumntype is used here only to make the column specifier easy to read.

May I know how to get "the magic number" -20, 46, -16?

Thank you in advance.

May I know how to get "the magic number" -20, 46, -16?

The command \rule[-20pt]{0pt}{46pt} prints an invisible rule (since it is 0pt wide) with a total height of 46 pt which starts 20 pt below the baseline. Characters in cells (except the fraction) are about 6 pt high. Adding 20pt above and 20pt below gives 46pt in total. Concerning -16pt, it is just a matter of trial and error.
