表の行の垂直方向の配置を変更する

表の行の垂直方向の配置を変更する

異なる行のセルの垂直方向の配置を変更する表を作成しようとしています。現時点では、すべての列が中央揃えになるように表を設定しています。ただし、最後の 2 行は上部で垂直方向に揃え、中央揃えではなく左揃え (つまり ではなく\raggedright) にしたいと\centering思います。これを実現する方法があるかどうか知りたいです。

私は TeX 初心者なので、私のコードはおそらくあまりきれいではないと思います。 何か助けていただければ幸いです。

私のコードは次のとおりです:

答え1

それぞれの細胞再調整したい行内で、

\multicolumn{1}{p{<len>}}{\raggedright <stuff>}

これにより、垂直方向の配置が上に、水平方向の配置がに調整されます\raggedright。固定幅のp列では、デフォルトでアンカー ポイントが上部に設定されます。

これは、パッケージ ( ) を使用したソリューションです。 は、のltablex機能を に追加します。 tabularx を使用すると、列の幅をわずかに広くすることができます。 また、およびコマンドを使用して、単位と数値を正しくタイプセットし、科学的記数法の略語を使用できるようにするために、 をロードしました (raggedright コンテキストでハイフネーションを有効にするため) 。コマンド (パッケージ) を使用すると、列見出しの共通フォーマットが可能になります。 最後に、から コマンドを体系的に使用して、化合物の簡単なタイプセットを実現しました。longtabletabularxragged2esinuitx\si, \SI\num\theadmakecell\cemhchem
