Muscular Basis 列のテキストがページ余白からはみ出さないようにしたいだけです。Muscular Basis 列の下のテキストの各行は、複数行にまたがって同じ行にすることができます。
答え1
\newcolumntypeこれは、次に示すように、列幅の 1 つの引数を持つコマンドで最後の列の列指定子を定義することで実現できます。
\newcolumntype{C}[1]{>{\raggedright \arraybackslash\hspace{0pt}}m{#1}}
m{#1}中央に縦にテキストが揃った段落列を意味します（パッケージが必要ですarray）
C{7cm}たとえば、ページの余白に当たらないように、最後の列の幅を決めることができます。
