我如何向该表添加另一列

这是另一个问题。

这是表格的代码

我怎样才能在右侧添加额外的柱子，就像张力柱一样？

答案1

  • 在表格右侧添加新列很简单，并在问题下方的评论中进行了解释
  • 因为您说新列与提供的 MWE 中的最后一列类似，所以只需重复此列规范并在该列中填充数据：
\documentclass{article}
\usepackage{geometry}
  \geometry{a4paper,
            showframe, % omit 'showframe' option in real document
            margin=20mm
  }
\usepackage{siunitx,booktabs}
\newcolumntype{T}[1]{S[table-format=#1]}

\begin{document}

\begin{center}
\sisetup{round-mode=places,round-precision=2} % <-- default: rounding to 2 decimal digits
\begin{tabular}{ @{}
                 T{1.2}
                 *{5}{T{2.2}}
                      S[table-format=2.3,round-precision=3]
                 *{2}{S[table-format=1.3,round-precision=3]} @{}}
 \toprule
 {Mass/ $m$, \unit{\kilo\gram}} &
 \multicolumn{6}{c}{Frequency/ $f$, \unit{\hertz} $\pm 0.001$}                  & {Tension} & ???   \\
 \cmidrule(lr){2-7}
        & {Trial 1} & {Trial 2} & {Trial 3} & {Trial 4} & {Trial 5} & {Average} &           &       \\
 \midrule
 0.050  & 16.200    & 16.630    & 16.560    & 16.840    & 16.550    & 16.556    & 0.491     &       \\
 0.100  & 23.650    & 22.800    & 22.810    & 22.970    & 22.700    & 22.986    & 0.981     &       \\
 0.150  & 28.060    & 27.650    & 27.600    & 27.470    & 27.440    & 26.644    & 1.472     &       \\

  • 或者如果你考虑我对你上一个问题的回答（到目前为止你还没有接受任何关于它的回答），那么表格序言中的变化如下：
