Graphics, Figures & Tables ⇒ Row Spacing in Tables

[thatoneguy]

Hi, I'm new to this forum but I've been using LaTeX for a few years now. I'm currently making a poster for school/work, and I'm having a problem with table row spacing. Specifically, I want to add a little bit of white space to the top of each cell in the table. But when I do that, the lines on the outside of the table ( The {|c | c | c |} lines, the vertical rules) do not scale accordingly.
To show you exactly what I mean, here is that portion of my code:

Code: Select all

\providecommand{\e}[1]{\ensuremath \times 10^{#1}}

\begin{tabular}{| c | c | c |}
\hline
\multicolumn{3}{| c |}{ Function of the form:}\\
\multicolumn{3}{| c |}{\hspace{3mm}$c_{0}+c_{1}(x-x_{c})+c_{2}(y-y_{c})+c_{3}(x-x_{c})^{2}+c_{4}(y-y_{c})^{2}+c_{5}(x-x_{c})(y-y_{c})$\hspace{3mm}}\\
\multicolumn{3}{| c |}{\vspace{-2mm}}\\
\hline
Variable & Assigned Value from Simulation & Fitted Value \\
\hline 
\noalign{\smallskip}$c_{0}$ & $0$ & $0.01005 \pm 6.08107 \e{-5}$  \\
\hline
\noalign{\smallskip}$c_{1}$ & $.001$ & $.00100 \pm 1.09939 \e{-7}$ \\
\hline
\noalign{\smallskip}$c_{2}$ & $.002$ & $.00200 \pm 1.09757 \e{-7}$ \\
\hline
$c_{3}$ & $9 \e{-7}$ & $8.99875 \e{-7} \pm 4.15653 \e{-10}$ \\
\hline
$c_{4}$ & $1.6 \e{-7}$ & $1.59903 \e{-7} \pm 4.15597 \e{-10}$ \\
\hline
\\[0.5cm]$c_{5}$ & $2.5 \e{-7}$ & $2.49560 \e{-7} \pm 3.70884 \e{-10}$ \\
\hline
\end{tabular}

I am working in the a0poster environment, though this problem isn't specific to that environment, I've experienced similar problems when working with the revtex4 environment as well.

The first 3 elements have the \noalign{\smallskip} thing; that provides the correct amount of whitespace, but look what it does to the vertical rules. The reason I need whitespace is, look at the exponents in the bottom 3 cells; it doesn't look quite right. This poster needs to look professional. I added in a different method of producing whitespace on the last row of cells. That has the same effect as \smallskip, but gives similar problems (except, some of the vertical rules scale, and some don't...)

I did not post my whole code because it is about 300 lines long. If it is necessary that I do post it, I can, I just wanted to avoid cluttering up this post unless it is necessary.

Does anyone know how I can fix this?

Thanks,

Problems are best shown by a proper minimal example.

Take a look at the array package and it's \extrarowheight command. Possible solutions should be found by a Forum Search.
