By default, it's challenging to use footnotes within tables in LaTeX because we can't predict where exactly in the document the table will end up. This uncertainty makes numbering footnotes within tables problematic.<7p>
However, with the help of the tabularx package, we can include footnotes within tables.
This LaTeX example demonstrates how to create a table with equally sized columns using the tabularx package. The table has four columns, each with a width of exactly 2cm. However, since the width is fixed, longer text in some cells may not be fully displayed.
Additionally, a footnote is added to the table. Footnotes are used to provide additional information or references without interrupting the main text. In this example, the footnote text "This is a footnote." is displayed at the bottom of the page.
\documentclass{article}
\usepackage{tabularx}
\begin{document}
\begin{tabularx}{8cm}{|X|X|X|X|}
\hline
In this table & each cell has & the same width & of exactly 2cm \\
\hline
And as you can see, & it's easy to notice & that this width & doesn't suffice for all columns
to display the entire text.\footnote{This is a footnote.} \\
\hline
\end{tabularx}
\end{document}
