表格乳胶中的额外一行

我想用 LaTeX 制作一个表格，我编写了以下程序：

\documentclass[]{article}
\usepackage{graphicx}
\usepackage{color}
\begin{document}

\begin {center}
\begin {tabular}{| l | l | l | l | l | l |}
\cline{2-6}
& \multicolumn{5}{ |c| }{$\eta_{\infty}$} \\  \cline{2-6}  
&  i=1,f=6 & i=1,f=3 & i=3,f=5& i=4,f=2& i=6,f=3 \\ \hline
$k,l=0,0$  & \textcolor{blue}{0.1811} & \textcolor{blue}{0.1811}&       \textcolor{blue}{0.1811}& \textcolor{blue}{0.1811}& \textcolor{blue}{0.1811} \\ \hline

\end {tabular}\\ 
 Table 2: System efficiency for different k,l and i,f.
\end {center}
\end{document}

有些单元格的第一列有一条多余的垂直线，我该如何省略它？感谢您尽快回复！

除了 David Carlisle 的解决方案之外，我宁愿取消所有垂直线，并使用booktabsandcellspace包。此包确保在带有前缀说明符的列中单元格顶部和底部的垂直间距最小S。我还使用了table environment, and a\caption` 命令，以便您可以交叉引用此表：

\documentclass[]{article}
\usepackage{graphicx}
\usepackage{array}
\usepackage{color}
\usepackage{cellspace, booktabs}
\setlength\cellspacetoplimit{4pt}

这是一个解决方案，它重新组织了第二个标题行中的材料，使其符合第一列的形式。它还使用S（包的siunitx）列类型将第 2 至第 6 列中的数字数据点对齐到小数点标记上。（我更改了一些数字，使它们在小数点标记后有两位或三位数字，以突出显示此设置的效果。）我进一步建议删除所有垂直规则和大多数水平规则；相信我，它们不会被错过。
