captionstables
If I don't put a caption on my table, I don't get the "Table 2.2" label underneath it. If I add a blank caption, I get "Table 2.2:". How do I get rid of the ":"?
I am using memoir and threeparttable. Within the threeparttable, I am using a tabular, but I don't think that matters.
An unorthodox solution: put the caption inside the tabularx environment (as would be done for longtable).
Some comments about your code: with threeparttablex, the tablenotes is replaced with TableNotes is declared at the very beginning, and is inserted later wheare you please with the \insertTableNotes commands. Also, if you really want to have a table with true X columns, you have to use the \keepXColumns command; else the calculated X width is only the maximum width of columns.
\documentclass{article}
\usepackage{array, ltablex}%
\usepackage{caption}
\usepackage{threeparttablex}
\setTableNoteFont{\footnotesize}
\usepackage{booktabs}
\keepXColumns
\begin{document}
\section{A First Section}
\begin{table}[ht]
\begin{ThreePartTable}
\begin{TableNotes}
\item[a] note1.
\item[b] note2.
\end{TableNotes}
\begin{tabularx}{\textwidth}{*{2}{X}}%
\toprule
\endhead
\bottomrule
\endfoot
ex1 & ex2\\
ex3 & ex4\\
\bottomrule
\insertTableNotes\\
\caption{Example1.}\label{tab:dummy}
\end{tabularx}%%
\end{ThreePartTable}
\end{table}
\begin{table}[ht]
\begin{ThreePartTable}
\begin{TableNotes}\footnotesize
\item[a] note1.
\item[b] note2.
\end{TableNotes}
\begin{tabularx}{\textwidth}{*{2}{X}}%
\caption{Example 2.}\label{tab:dummy}\\
\toprule
\endhead
\bottomrule
\endfoot
ex1 & ex2\\
ex3 & ex4\\
\bottomrule
\insertTableNotes\\
\end{tabularx}%%
\end{ThreePartTable}
\end{table}
\end{document}
Adding \caption{} to a table adds an unwanted table separator to the caption. For example, you might end up with a caption:
Table 1:
You can control this, for example, with the package caption. For example:
\documentclass{article}
\usepackage{booktabs}
\usepackage[labelsep=none]{caption}
\begin{document}
\begin{table}
\centering
\begin{tabular}{cc}
\toprule
left number & right number \\
\midrule
5.6 & 3.8 \\
1.3 & 20.4 \\
10.4 & 5.2 \\
1.3 & 0.8 \\
7.2 & 3.9 \\
2.5 & 16.2 \\
\bottomrule
\end{tabular}
\caption{}
\label{tab:tab}
\end{table}
Let's refer to Table~\ref{tab:tab}.
\end{document}
The caption now reads:
Table 1
If there are other tables that need an ordinary caption, you can use \captionsetup to temporarily change options. See the documentation for more details.
The package also contains further options to control the caption. For example, if you really want only the number (without "Table" in front) under the table, you can use:
\documentclass{article}
\usepackage{booktabs}
\usepackage[labelsep=none,labelformat=empty]{caption}
\begin{document}
\begin{table}
\centering
\begin{tabular}{cc}
\toprule
left number & right number \\
\midrule
5.6 & 3.8 \\
1.3 & 20.4 \\
10.4 & 5.2 \\
1.3 & 0.8 \\
7.2 & 3.9 \\
2.5 & 16.2 \\
\bottomrule
\end{tabular}
\caption{\ref{tab:tab}}
\label{tab:tab}
\end{table}
Let's refer to table~\ref{tab:tab}.
\end{document}
