我正在尝试更改带有表格的 Latex 文档的字体大小，但似乎不起作用。我尝试过文档类别“book”和“article”。这是我的代码

Allgemeine Formel: $f \cdot S \cdot s \cdot \frac{l}{K}$ \\
$f$ – Integrationskoeffizient \\
$S$ – repräsentativer Wert erster Schnittgrösse \\
$s$ – repräsentativer Wert zweiter Schnittgrösse \\
$l$ – Stablänge \\
$K$ – Steifigkeit ($EA$, $EI$, $GA_v$ etc.) \\
