程序包 PGF 数学错误：无法将输入解析为浮点数

我正在尝试格式化这个漂亮的表格作为答案到漂亮的表格样本。如果您查看第三列，您会发现单位为 eV。我想将十的幂的 latex 公式添加到此列，但这样做时会收到错误消息：

Package PGF Math Error: Could not parse input '$10^6$' as a floating point number.

我该怎么做才能将乳胶数学插入此列？谢谢！

我看不出有什么问题。但有三种方法可以实现你想要的

column name={$E_{\textup{g}}$ (\si{\mega\electronvolt})},


column name={$E_{\textup{g}}$ (\si{10^6\cdot\electronvolt})},


    diamond         & C      & 5.46e6 & i \\
    silicon         & Si     & 1.12e7 & i \\
    germanium       & Ge     & 0.67e8 & i \\
    selenium        & Se     & 1.74e9 & d \\
