我正在尝试根据数字动态分配表格中的行高，具体来说是课堂课程中用于特定活动的分钟数。表格表示课程计划被分成几个部分，大行表示较长的活动，短行表示较短的活动等。我知道如何通过在行尾使用 \[2em] 来调整行高，但我宁愿从第 1 项计算此值，因为行高应与活动中的分钟数成比例，我还计算了累计总数，以便教师可以轻松了解课程每个部分的开始时间、开始时间，这样就很好了。
请参阅 \R 的定义，我为此奋斗了几天却没有任何进展，如能得到任何帮助我将不胜感激。

\rule[\dimexpr9pt-#1\hunits\relax]{0pt}{#1\hunits}我所做的就是在 的第一列定义中添加\R，其中\hunits选择 以满足总体高度（时间）约束。在本例中，\hunits设置为 3.5 pt，这意味着课程的每一分钟都会获得 3.5pt 的垂直空间。

请注意，如果多行单元格（如“学习活动”）太长，它可能会（并且确实会）超出规则设置的垂直高度。我通过将规则宽度设为 1pt 来在下面展示此情况：
