Latex table is not formatting properly

Question

I need tiny help! My latex table is not getting formatting Properly! Anyone can help me How I can fix the issue?

Latex Code is

\begin{table}
\centering
\caption{Hardness comparison}
\begin{tabular}{|c|c|c|c|c|c|} 
\hline
\begin{tabular}[c]{@{}c@{}}\textbf{BFO} \\\textbf{K\_\$\{IC\}\$(MPa.m\textsuperscript{0.5})} \\\textbf{Niihara´s eq.} \\\textbf{~}\end{tabular} & \begin{tabular}[c]{@{}c@{}}\textbf{BLFO} \\\textbf{\textbf{K\_\$\{IC\}\$}(MPa.m\textsuperscript{0.5})} \\\textbf{Niihara´s eq.}\end{tabular} & \begin{tabular}[c]{@{}c@{}}\textbf{BFNbO} \\\textbf{\textbf{K\_\$\{IC\}\$}(MPa.m\textsuperscript{0.5})} \\\textbf{Niihara´s eq.}\end{tabular} & \begin{tabular}[c]{@{}c@{}}\textbf{BFO} \\\textbf{\textbf{K\_\$\{IC\}\$}~(MPa.m\textsuperscript{0.5})} \\\textbf{Anistis´s eq.}\end{tabular} & \begin{tabular}[c]{@{}c@{}}\textbf{BLFO} \\\textbf{\textbf{K\_\$\{IC\}\$}~(MPa.m\textsuperscript{0.5})} \\\textbf{Anistis´s eq.}\end{tabular} & \begin{tabular}[c]{@{}c@{}}\textbf{BFNbO} \\\textbf{\textbf{K\_\$\{IC\}\$}~(MPa.m\textsuperscript{0.5})} \\\textbf{Anistis´s eq.}\end{tabular}  \\

Please make your code compilable by adding the documentclass as well as the relevant packages (See also: minimal working example (MWE)) Since the most obvious issue with your table is the fact that it exceeds the available text width, you may be interested in taking a look at: My table doesn't fit; what are my options? — leandriis, Mar 22 '22 at 14:41
In order to save some space in your table, you may want to consider removing the repeated \textbf{K\_\$\{IC\}\$(MPa.m\textsuperscript{0.5})}. You could probably explain it in the caption of your table, instead. Likewise, I'd suggest using shared column headers in order to avoid repeating the names of the equations. — leandriis, Mar 22 '22 at 14:45
Is the reason for all those \begin{tabular}[c]{@{}c@{}} solely so that you can have a few newlines? — Teepeemm, Mar 22 '22 at 14:45
Problem Has been the Same! Yet not get solved after replacing the code! — Sagarkumar Zalavadiya, Mar 22 '22 at 14:49
Off topic: K\_\$\{IC\}\$ looks weird. Are you sure you don't want K\textsubscript{IC}? — Teepeemm, Mar 22 '22 at 16:08

Table, as you have now, if far to wide that can be fit on page. Also in firsr row you in each cell repeat data \textbf{K\_\$\{IC\}\$(MPa.m\textsuperscript{0.5}). You may consider to move this for example in caption of table, for example as >I done in MWE below (well, context and meaning of table headers is unknown to me, so you probably should rephrase caption text).

By use of the tabularray package with siunitx library (which load siunitx package), you can write your document example as follows:

\documentclass{book}
\usepackage[showframe]{geometry}
\usepackage{tabularray}
\UseTblrLibrary{siunitx}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
    \begin{table}[ht]
\caption{Comparison of the K_IC hardness measured in  (\unit{\mega\pascal\sqrt{m}})}
\begin{tblr}{hlines, vlines,
             colspec = {*{6}{X[c, si ={table-format=1.2}]}},
              colsep = 4pt,
              row{1} = {font=\small\bfseries}
             } 
{{{BFO\ Niihara´s eq.}}}
        &   {{{BLFO\ Niihara´s eq.}}}
                &   {{{BFNbO\ Niihara´s eq.}}}
                        &   {{{BFO\ Anistis´s eq.}}}
                                &   {{{BLFO\ Anistis´s eq.}}}
                                        &   {{{BFNbO\ Anistis´s eq.}}}   \
0.19    & 0.10  & 0.04  & 0.18  & 0.08  & 0.04      \
0.25    & 0.09  & 0.22  & 0.17  & 0.07  & 0.16      \
0.19    & 0.37  & 0.09  & 0.17  & 0.24  & 0.08      \
0.27    & 0.28  & 0.29  & 0.27  & 0.28  & 0.28      \
\end{tblr}
    \end{table}
\end{document}

If suggested solution is not acceptable to you, the only reasonable option is rotate table into landscape orientation.

You really need to simplify the header cells, as they contain lots of redundancies that make them unreadable and the table much too wide.

I suggest something like the following.

\documentclass{article}
\usepackage{array,booktabs,siunitx}
\usepackage[flushleft]{threeparttable}
\begin{document}
\begin{table}
\centering
\begin{threeparttable}
\caption{Hardness comparison\tnote{*}}
\begin{tabular}{@{} cccccc @{}} 
\toprule
\multicolumn{3}{@{}c}{Niihara's eq.} & 
\multicolumn{3}{c@{}}{Anistis's eq.} \\
\cmidrule(r){1-3} \cmidrule(l){4-6}
BFO & BLFO & BFNbO & BFO & BLFO & BFNbO \\
\midrule
0.19 & 0.10 & 0.04 & 0.18 & 0.08 & 0.04 \\ 
0.25 & 0.09 & 0.22 & 0.17 & 0.07 & 0.16 \\ 
0.19 & 0.37 & 0.09 & 0.17 & 0.24 & 0.08 \\ 
0.27 & 0.28 & 0.29 & 0.27 & 0.28 & 0.28 \\
\bottomrule
\end{tabular}
\footnotesize
\begin{tablenotes}
\item[*] K_${IC}$(MPa.m\textsuperscript{0.5}), or 
   maybe K\textsubscript{IC} (\unit{\mega\pascal\meter\tothe {0.5}})
\end{tablenotes}
\end{threeparttable}
\end{table}
\end{document}
