Vertical table lines are discontinuous with booktabs

Question

I created a table in LaTeX, but there are some problems with the borders. The borders remain open whereas I want them closed. Also, in the last row, I want the vertical line gone, ie I want just one column in the last row. Can someone please fix it? Here are my code and my table:

Answer 1

I don't think the answer "Don't use vertical rules" is very constructive when the question is about making vertical lines look nice. So here is a solution if you only want to modify the width of horizontal lines and if you are willing to not use booktabs:

\midrule , \toprule , and \bottomrule are replaced by \noalign{\hrule height 1.5pt} with the width that you want.

You can also set the width of vertical lines by using !{\vrule width 2pt} instead of | in the tabular parameters.

I understand that this solution is not optimal, but it can do the trick and I hope it would help.

Answer 2

That's by design: the author of booktabs hates vertical rules in tables and I fully agree with him. You could act on spacing parameters, namely

• \abovetopsep (0pt by default), used above a \toprule
• \belowbottomsep (0pt by default), used below a \bottomrule
• \aboverulesep (0.4ex by default), used above a \midrule, \cmidrule or \bottomrule
• \belowrulesep (0.65ex by default), used below a \midrule, \cmidrule or \toprule

They are all rigid length (no plus or minus specifications are allowed and they wouldn't make sense anyway).

By (locally) setting these parameters to zero, the vertical rules will match, but it would simpler not to use booktabs commands at all: the heavier \toprule and \bottomrule would be completely out of place.

Don't use vertical rules and the appearance of your table will improve immediately.

I've made some notable changes.

1. The subscripts are upright, being words

2. The alignment is improved by using features of the table itself; for instance, the third and fifth column are right aligned because of the minus signs only in the first coordinate; it wouldn't be so if the minus sign appeared also in the second coordinate or the headers had been wider.

3. With \cmidrule it's easier to show how the headers group the columns.

4. A trick is used for avoiding the * to take up space.

5. An array trick is used for setting all columns in math mode, ensuring that the minus signs are printed as such.

6. \centering is used instead of the center environment (that adds vertical space).

If you need to change "95% CI" to "95% Bayesian Interval", the best is to split the long phrase into two lines: modify the block

\multicolumn{1}{c}{Coefficient} &
\multicolumn{1}{c}{95\% CI}     &
\multicolumn{1}{c}{Coefficient} &
\multicolumn{1}{c}{95\% CI}     \\
\midrule

into

\multicolumn{1}{c}{Coefficient} & \multicolumn{1}{c}{95\% Bayesian} &
\multicolumn{1}{c}{Coefficient} & \multicolumn{1}{c}{95\% Bayesian} \\
                                & Interval                          &
                                & Interval                          \\

Answer 3

As @Puck says in his answer, and as Brandon Kuczenski comments, the responses here are not constructive, neither the question is answered.

The way to use vertical lines with booktabs (despite it is discouraged), is to reduce the space above and below the midrule:

 \aboverulesep=0ex
 \belowrulesep=0ex

This will cramp your tables a little bit, so, to return to a regular table line height, you should stretch your array with:

\renewcommand{\arraystretch}{SF}

Where SF is the stretch factor (use SF>1.0).

Just in case, you should add those lines in the preamble.

Hope this does answer your question.

Answer 4

booktabs also offers the specialrule like so:

\specialrule{\cmidrulewidth}{0pt}{0pt}

which will produce a horizontal line with no spacing and the vertical lines will cross it neatly.

Answer 5

Vertical lines are always continuous with the rules of booktabs if you use tblr or talltblr or longtblr environment of tabularray package:

Answer 6

My solution was to follows user215982's suggestion of \aboverulesep=0ex and \belowrulesep=0ex. However, I wanted to avoid the gaps between table rows caused by \renewcommand{\arraystretch}{1.35}. Instead, to put back the required vertical spacing, I placed vertical struts \rule{0pt}{1.1EM} in the row for the column headings and in the 1st row of data in the table.

\documentclass{article}
\usepackage{booktabs}
%\renewcommand{\arraystretch}{1.35} % Not part of my solution
\begin{document}
\begin{table}\centering
   \aboverulesep=0ex % Solution part 1 of 3
   \belowrulesep=0ex % Solution part 1 of 3
   \caption{Example records from a data frame.}
   \begin{tabular}[t]{ccc|ccc}
   \toprule
       \rule{0pt}{1.1EM}% Solution part 2 of 3 (% is required)
       XXXX & XXX\_XXXX & XXXXXX & XXXX & XXX\_XXXX & XXXXXX \\
   \midrule
       \rule{0pt}{1.1EM}% Solution part 3 of 3 (% is required)
       XXXX & XXX       &  XXX   & XXXX & XXX       &  XXX   \\
       XXXX & XXX       &  XXX   & XXXX & XXX       & XXXX   \\
       XXXX & XXX       &  XXX   & XXXX & XXX       &  XXX   \\
       XXXX & XXX       &  XXX   \\
   \bottomrule
   \end{tabular}
\end{table}
% This just helps visualize the effect of \rule parameters
\rule{3mm}{.1pt}%
\rule[-1mm]{5mm}{1cm}%
\rule{3mm}{.1pt}%
\rule[1mm]{1cm}{5mm}%
\rule{3mm}{.1pt}%
\rule{1cm}{5mm}%
\rule{3mm}{.1pt}
\end{document}

The result is what I sought:

Please help improve this answer: My visual inspection seems to confirm that placing the commands \aboverulesep=0ex and \belowrulesep=0ex between \begin{table} and \end{table} keeps the commands local. It would help if those more familiar with LaTeX confirm this explicitly. Thanks.

Answer 7

I trimmed it a little, added small spaces between every 4th row, and used short forms for the titles, and right aligned the first column, to tighten it.

If you actually want vertical rules compatible with the rules of booktabs (which is not at all in the spirit of booktabs), you should use {NiceTabular} of nicematrix.

\documentclass{article}
\usepackage{nicematrix}
\usepackage{booktabs}
\usepackage{caption}
\usepackage{enumitem}
\begin{document}
\begin{table} [h!]
\centering
\begin{NiceTabular}{|l|c|c|c|c|}
\toprule
Parameters  & \multicolumn{2}{c}{Model 1} & \multicolumn{2}{c}{Model 2}\ 
\midrule

    $\beta_{breath_2}$  &  0.157 & (0.07,8 0.236) & 0.208 & (0.136, 0.280) \

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).
