縦向きモードでは、テーブルをテキスト幅よりも広くする必要があります。geometry提案されたパッケージを使用するここテーブルが新しいページで始まるため、これは実行不可能です。ただし、テキストフロー内に配置したいです。長いテーブルをテキスト幅よりも広くする方法はありますか?
答え1
\LTleftと\LTrightの値を変更します。例えば、
\setlength\LTleft{-40pt}
\setlength\LTright{-40pt}
答え2
xltabular同じ名前の環境を持つパッケージを使用します。
\documentclass[DIV=8,captions=tableabove]{scrartcl}
