删除了框之间的线

Question

我有一张桌子

\begin{tabular}{|c|c|c|c|c|c|c|c|c|}%l -> left, c -> center, r -> right     
        \hline\cellcolor{blue!25}  &\cellcolor{blue!25} &\cellcolor{blue!25} E\cellcolor{blue!25} &\cellcolor{blue!25} H\cellcolor{blue!25} &\cellcolor{blue!25} \_ &\cellcolor{blue!25}T&\cellcolor{blue!25}M&\cellcolor{blue!25}U&\cellcolor{blue!25}N \\

我该如何解决这个问题？

Answer 1

这取决于观察者的放大倍数。但是，请使用每列的\rowcolor倍数。\cellcolor

\documentclass{scrbook}
\usepackage[table]{xcolor}   
\begin{document}

\begin{tabular}{|c|c|c|c|c|c|c|c|c|}\hline
\rowcolor{blue!25}  & & E & H & \_ & T & M & U & N \\
\end{tabular}

\end{document}
