我在 beamer 中使用footcitetext和和footnotemark。编号有些问题，因为一个 footnotemakr 是正常定义的，而另一个在 columns 环境中
\documentclass[aspectratio=169]{beamer} \setbeamertemplate{navigation symbols}{} \setbeamertemplate{caption}[numbered]
\usepackage{amsmath,bm} \usepackage{amssymb} \usepackage{tabularx} \usepackage{multirow} \usepackage{booktabs} \usepackage{esint} \usepackage{graphicx} \usepackage{xcolor} \usepackage{pgfplots} \usepackage{tikz} \usepackage{tikzscale}
\usepackage[style=authortitle,backend=bibtex]{biblatex} \addbibresource{bibliography.bib}
\begin{document}
\begin{frame}{Title}{}
Some text here \footnotemark
\begin{columns}
\column{0.5\textwidth}
\begin{itemize} \item 1 \footnotemark \item 2 \item 3 \end{itemize}
\column{0.5\textwidth}
\begin{itemize} \item item 1 \item item 2 \item item 3 \end{itemize}
\end{columns}
\footcitetext{desantes2020comparative} \footcitetext{site1}
\end{frame}
\end{document}

\footcitemark/text对于不在列内的脚注，无需使用解决方法：
\documentclass[aspectratio=169]{beamer} \setbeamertemplate{navigation symbols}{} \setbeamertemplate{caption}[numbered]
\usepackage{amsmath,bm} \usepackage{amssymb} \usepackage{tabularx} \usepackage{multirow} \usepackage{booktabs} \usepackage{esint} \usepackage{graphicx} \usepackage{xcolor} \usepackage{pgfplots} \usepackage{tikz} \usepackage{tikzscale}
\usepackage[style=authortitle,backend=bibtex]{biblatex} \addbibresource{bibliography.bib}
\begin{document}
\begin{frame}{Title}{}
Some text here \footcite{desantes2020comparative}
\begin{columns}
\column{0.5\textwidth}
\begin{itemize} \item 1 \footnotemark \item 2 \item 3 \end{itemize}
\column{0.5\textwidth}
\begin{itemize} \item item 1 \item item 2 \item item 3 \end{itemize}
\end{columns}
\footcitetext{site1}
\end{frame}
\end{document}
