Graphics, Figures & Tables ⇒ How to change the font of the headers?

[DryRun]

Hi,

How to change the headers so that it is not italic but instead bold?

Code: Select all

\begin{tabular}{ @{} l l l >{$\mathstrut\displaystyle}l<{$} @{} }\toprule 
\emph{first} & \emph{second} & \emph{third} & \multicolumn{1}{l}{\emph{fourth}} \\\midrule
foo & bar & y=f(x) & data\\
foo & bar & y=f(x) & data \\
foo & bar & Time \\
foo & bar & y=f(x) & 10.56 \\
foo & bar & Angle & 18.256 \\
foo & bar & Force & 1.6 \\
foo & bar & y=f(x) & 8.56 \\\bottomrule
\end{tabular}

emph makes it italic.

Thanks for the hint. I changed it to \textbf

The tex file compiles with no errors in Overleaf but i'm puzzled over why this part of the code is highlighted in red:

Code: Select all

$\mathstrut\displaystyle}l<{$}

Is this a deprecated style??

I have no idea why Overleaf highlights it read. I don't use Overleaf.

Code: Select all

\documentclass{article}
\usepackage{booktabs}
\usepackage{array}
\begin{document}
\begin{tabular}{ @{} l l l >{$\mathstrut\displaystyle}l<{$} @{} }
\toprule 
\emph{first} & \emph{second} & \emph{third} & \multicolumn{1}{l}{\emph{fourth}} \\\midrule
foo & bar & y=f(x) & data\\
foo & bar & y=f(x) & data \\
foo & bar & Time \\
foo & bar & y=f(x) & 10.56 \\
foo & bar & Angle & 18.256 \\
foo & bar & Force & 1.6 \\
foo & bar & y=f(x) & 8.56 \\\bottomrule
\end{tabular}
\end{document}

Don't post code chunks, always a complete and compilable document.
