I have following table which I need to include in a beamer presentation :
I have read this post . I think I only need to adjust in this \begin{tabular}{*{27}{l}}. But I don't know how is to do that ?
EDIT: The data are given for convenience
\begin{table}[H]
\scalebox{0.83}{
\begin{tabular}{cccccccccc}
\hline\hline
Number of groups & Group size & ICC & $\sigma_{u0}$ & $\sigma_{u1}$ & $\sigma_{e}$ & $\gamma_{00}$ & $\gamma_{10}$ & $\gamma_{01}$ & $\gamma_{11}$\\
