Hi I need some help running this table.
Here are my codes
\begin{center}
\begin{tabular}{lcc}
\hline \noalign{\smallskip} & mpg & mpg & mpg\\
\noalign{\smallskip}\hline \noalign{\smallskip}weight & -.0060087 & -294.196 & 4\\
& \begin{footnotesize}(4.50)**\end{footnotesize} & \begin{footnotesize}(5.28)**\end{footnotesize}\\
\noalign{\smallskip}foreign & & 1,767.292 & 5\\
& \begin{footnotesize}(4.50)**\end{footnotesize} & \begin{footnotesize}(5.28)**\end{footnotesize}\\
\noalign{\smallskip}foreign*weight & & & 1,767.292\\
& \begin{footnotesize}\end{footnotesize} & \begin{footnotesize}(2.52)*\end{footnotesize}\\
\noalign{\smallskip}\_cons & 11,253.061 & 11,905.415 & 7\\
& \begin{footnotesize}(9.61)**\end{footnotesize} & \begin{footnotesize}(10.28)**\end{footnotesize}\\
\noalign{\smallskip}$R^2$ & 0.22 & 0.28 & 7\\
$N$ & 74 & 74 & 7\\
\noalign{\smallskip}\hline\end{tabular}\\
\smallskip\begin{footnotesize}\ * $p<0$.05; ** $p<0$.01\end{footnotesize}\\
\smallskip
\end{center}

tabular, but only specify 3 in{lcc}. For footnotes, see Footnotes in tables? – Werner Jan 31 '15 at 19:41tabularinside atableenvironment, notcenter.
