我在投影仪幻灯片中使用长表格，因此尝试使用框架中的 allowframebreaks 命令将它们分布到多张幻灯片上。长表格显示正常，但是，在框架末尾的输出中添加了一个空白幻灯片。我该如何避免这种情况？

答案1
有几个问题：
如果您想使用
\degree宏，您必须定义它或加载提供它的包之一。 Overleaf 非常擅长隐藏错误消息，但右上角应该有一个红色方块提醒您有错误。 如果 latex 遇到错误，它只会检查文档的其余部分，而不一定会产生合理的输出你的表格也太宽了，无法放在框架上。你可以通过缩小最后一列来节省一点空间
即使 beamer 没有浮动机制，
tableetc 等环境也不打算跨越多张幻灯片。正如您注释掉的标题一样，它实际上也没有什么用处。删除它。您无需加载
color，hyperref或者etoolbox，beamer 会为您加载使用最新的 latex，你也不需要
\usepackage[utf8]{inputenc}，这是默认的不要多次加载同一个包
与 latex 无关，但你确定在演示中真的需要这么长的表格吗？观众几乎不会记住所有的数字。通常，展示你从表格中学到的东西比展示表格更好。如果你真的必须包含表格，请查看软件包的文档，
booktabs了解如何创建专业的表格。
