Graphics, Figures & Tables ⇒ How to vertically center math objects in a table cell?

[yoyoimut]

Dear all,

I am creating a table of formulae. The left column is for numbering and the right one is for the formula.

My question is how to vertically center the formula without using a magic constant obtained from trial and error adjustment?

Here is my code snippet that has been simplified.

Code: Select all

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{array,longtable}


\newcounter{counter}
\renewcommand{\thecounter}{\stepcounter{counter}\raisebox{-0.63\depth}{\color{red}\bf\Large\arabic{counter}.}}
\newcolumntype{L}{>{\thecounter}r}
\newcolumntype{R}[1]{>{\parbox[c][#1][c]{0mm}{}\color{red}\Large\centering\arraybackslash$\displaystyle}m{0.5\linewidth}<{$}}



\begin{document}
\begin{longtable}{|L|R{15mm}|}\hline
\multicolumn{1}{|>{\Large\color{red}\bf}c|}{No} & \textrm{Equation}\\\hline
&  	\nabla\cdot\mathbf{D}=\rho_f \\\hline
&  	\nabla\cdot\mathbf{B}=0 \\\hline
&  	\nabla\times\mathbf{E}=-\frac{\partial \mathbf{B}}{\partial t} \\\hline
&  	\nabla\times\mathbf{H}=\mathbf{J}_f+\frac{\partial \mathbf{D}}{\partial t} \\\hline
&  	\int_a^b f(x)\, dx=F(b)-F(a) \\\hline
&		\sin x\\\hline
&  	\nabla\cdot\mathbf{D}=\rho_f \\\hline
&  	\nabla\cdot\mathbf{B}=0 \\\hline
&  	\nabla\times\mathbf{E}=-\frac{\partial \mathbf{B}}{\partial t} \\\hline
&  	\nabla\times\mathbf{H}=\mathbf{J}_f+\frac{\partial \mathbf{D}}{\partial t} \\\hline
&  	\int_a^b f(x)\, dx=F(b)-F(a) \\\hline
&		\sin x\\\hline
&  	\nabla\cdot\mathbf{D}=\rho_f \\\hline
