Complete vertical lines in LaTeX table

Question

The following code:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{chemfig}
\usepackage{booktabs}
\usepackage{multirow}
\usepackage{caption}
\begin{document}
\maketitle
% Table generated by Excel2LaTeX from sheet 'Hoja1'
\begin{table}[htbp]
  \centering
  \caption{Add caption}
    \begin{tabular}{|c|c|c|}
    \toprule
    \multicolumn{1}{|p{5.215em}|}{Case Study} & \multicolumn{1}{p{4.57em}|}{H2O inlet (m/s)} & \multicolumn{1}{p{4.5em}|}{CO2 inlet (m/s)} \
    \midrule
    1     & \multirow{3}[6]{}{0.05} & 0.75 \
\cmidrule{1-1}\cmidrule{3-3}    2     &       & 1 \
\cmidrule{1-1}\cmidrule{3-3}    3     &       & 1.5 \
    \midrule
    4     & \multirow{3}[6]{}{0.075} & 0.75 \
\cmidrule{1-1}\cmidrule{3-3}    5     &       & 1 \
\cmidrule{1-1}\cmidrule{3-3}    6     &       & 1.5 \
    \midrule
    7     & \multirow{3}[6]{*}{0.1} & 0.75 \
\cmidrule{1-1}\cmidrule{3-3}    8     &       & 1 \
\cmidrule{1-1}\cmidrule{3-3}    9     &       & 1.5 \
    \bottomrule
    \end{tabular}%
  \label{tab:addlabel}%
\end{table}%
\end{document}

Produces the table shown in the picture.

I would like to complete the vertical lines. What can I do?

please see the booktabs package documentation it explicitly documents that vertical rules should not be used with the package. — David Carlisle, Dec 04 '21 at 17:13

The booktabs manual says "never, ever use vertical rules".

You can, however, reduce the spaces in the vertical rules along the lines of:

\setlength{\aboverulesep}{0.1ex}  % default 0.4ex
\setlength{\belowrulesep}{0.1ex}  % default 0.65ex

Doing this, of course defeats the purpose of the booktabs package, but that is up to you

Simply don't use booktabs at all and switch to \hline and \cline. Note your auto-generated markup is a bit overly complicated.

\documentclass{article}
\usepackage{multirow}
\begin{document}
\begin{tabular}{|c|c|c|}
\hline
Case Study & H2O inlet (m/s) & CO2 inlet (m/s) \
\hline
1     & \multirow{3}{}{0.05} & 0.75 \
\cline{1-1}\cline{3-3}    2     &       & 1 \
\cline{1-1}\cline{3-3}    3     &       & 1.5 \
\hline
4     & \multirow{3}{}{0.075} & 0.75 \
\cline{1-1}\cline{3-3}    5     &       & 1 \
\cline{1-1}\cline{3-3}    6     &       & 1.5 \
\hline
7     & \multirow{3}{*}{0.1} & 0.75 \
\cline{1-1}\cline{3-3}    8     &       & 1 \
\cline{1-1}\cline{3-3}    9     &       & 1.5 \
\hline
\end{tabular}
\end{document}

If you do want to use booktabs you really should remove the vertical lines and go with something like

\documentclass{article}
\usepackage{multirow, booktabs}
\begin{document}
\begin{tabular}{ccc}
\toprule
Case Study & H2O inlet (m/s) & CO2 inlet (m/s) \
\midrule
1     & \multirow{3}{}{0.05} & 0.75 \
2     &       & 1 \
3     &       & 1.5 \
\midrule
4     & \multirow{3}{}{0.075} & 0.75 \
5     &       & 1 \
6     &       & 1.5 \
\midrule
7     & \multirow{3}{*}{0.1} & 0.75 \
8     &       & 1 \
9     &       & 1.5 \
\bottomrule
\end{tabular}
\end{document}

Vertical lines at packages nicetabular and tabularray works well with rules defined in the booktabs package. For example, MWE using tabularray and S column type in columns with numbers, is:

\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}
\usepackage{chemfig}  % if needed
\usepackage[version=4]{mhchem}
\usepackage{caption}
\begin{document}
    \begin{table}[ht]
    \sisetup{per-mode = symbol}
    \centering
\caption{Add caption}
\label{tab:addlabel}
    \begin{tblr}{hline{2-Y}, vlines,
                 colspec = {Q[c,m, wd=5em] 
                            Q[c,m, si={table-format=1.3}, wd=5em]
                            Q[c,m, si={table-format=1.2}, wd=5em]}
                 }
    \toprule
{Case\ Study}
    & {{{ \ce{H2O} inlet\ (\si{\meter\per\second}) }}}
        & {{{\ce{CO2} inlet\ (\si{\meter\per\second})}}}   \
1   & \SetCell[r=3]{m}  0.05    & 0.75  \
2   &                           & 1     \
3   &                           & 1.5   \
4   & \SetCell[r=3]{m}  0.075   & 0.75  \
5   &                           & 1     \
6   &                           & 1.5   \
7   & \SetCell[r=3]{m}  0.1     & 0.75  \
8   &                           & 1     \
9   &                           & 1.5   \
    \bottomrule
    \end{tblr}
    \end{table}
\end{document}
