# Reference to a table before it appears

I want to reference a table before it appears.The TeX code is pasted below

\documentclass{article}
\begin{document}
The results given in Table~\ref{tab:a} show the  performance of
the class.

\begin{table}
\begin{center}
\begin{tabular}{lrc}\hline
Name & Mark & Grade \\
\hline
Prasad & 99 & A+ \\
Prakash & 51 & C\\
Shine & 5 & F\\ \hline
\end{tabular}
\caption{Class Mark List}\label{tab:a}
\end{center}
\end{table}
\end{document}


But the text

The results given in Table~\ref{tab:a} show the  performance of
the class.


is coming after the table. How can I put the table immediately after the text.

Is this a problem of where the table appears (float placement) or of referencing it? You can influence the placement of the table with a modifier \begin{table}[h]. (I believe the \label should go inside the \caption.) –  Christian Lindig Feb 27 '11 at 10:24
@Christian: The \label just needs to go after the \caption. I can't think of any good reason to put it inside it. –  TH. Feb 27 '11 at 10:34

@Christian. I want the table to be referenced before and place the table immediately after the text. –  Vinod Feb 27 '11 at 10:37

use it this way:

\begin{table}[!htb]
\centering
\begin{tabular}{lrc}\hline
....
\caption{Class Mark List}\label{tab:a}
\end{table}

Thanks.[h] is also working. –  Vinod Feb 27 '11 at 10:41
@Vinod: I know, but in other situations not and it is already modified internally to [ht] –  Herbert Feb 27 '11 at 10:42
\begin{table}[htdp]
\vskip 0.25cm
\begin{center}
\begin{tabular}{| c| c |c |}
\hline\hline
{\textcolor{blue}{Plasma Parameter} & {\textcolor{blue}{PIC code parameters }& { \textcolor{blue}{MHD code parameters}}&\\
\hline
{\bf B$_z$}& 0.2&6.5 (nT)\\
\hline
{\bf V$_x$}& 0.25 & 500 (km.sec$^-^1$)\\
\hline
{\bf V$_A$}& 0.028 & 63 (km.sec$^-^1$)\\

Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. Could you provide some explanations? Also, it would be better to have a full compilable code instead of just a snippet. –  henrique Aug 24 at 15:32
