[Tugindia] Could we able to increase the default dimension?

[Dr. M. Kalidoss]

Baskaran may want to try the the following file, 
to fix the dimension of the caption:

\documentclass{article}

\begin{document}
\renewcommand{\baselinestretch}{1.6}\small\normalsize

\begin{table}[htbp]
\parbox[c]{5.4cm}{\caption{Force constant parameters of Sample~1  and
Sample~2  in units of 10$^{4}$~dyne cm$^{ - 1}$.}}
%\\          	%%% Remove the % sign at the beginning of this line and see the result!
\begin{tabular}{||c|cc||}
\hline\hline
Symbol& \multicolumn{2}{c||}{Value for} \\
\cline{2-3}
      & Sample~1 & Sample~2 \\
\hline
A& -3.2992& -5.9960 \\
B& -2.64017& -4.54166 \\
E& -4.2283& - 5.8750 \\
C& -1.6379& -1.2600 \\
D& -0.3176& 0.0400 \\
A$_{2}$& -1.4391& -1.9600 \\
B$_{2}$& -0.2854& 0.0770 \\
