在表格中逐一显示元素

Question

我想逐个为元素着色。在我的示例中，我只想先将 3 涂成蓝色，而不是 3,0。该怎么做？

\begin{table}
    \centering
    \begin{tabular}{|c|c|c|} 
        \toprule
        \diagbox{Player 1}{Player 2} & Left (L)~~ & Right (R)~ ~  \\ 
        \hline
        Up (U)                       & \color<2->{blue}{3},0        & 0,-4          \\ 
        \hline
        Down (D)                     & 2,4        & -1,8          \\
        \bottomrule
    \end{tabular}
\end{table}

Answer 1

使用{\color<2->{blue}{3}},0应该会产生预期的输出：

由于包中的行booktabs与垂直线不兼容，因此我在最终的 MWE 中还包含了两种替代表格布局：
