Excel 自动调整行高不适用于带自动换行的合并单元格

Question

我以编程方式将一些文本连续插入到合并的单元格中。我设置了 Wrap Text 并希望根据需要扩展行高以容纳多行文本。填充单元格后，我以编程方式应用 AutoFit，但这没有用。我随后发现一篇知识库文章说 AutoFit 不适用于合并的单元格!我可以尝试计算容纳换行文本行数所需的行高。但我真的不想深入计算字符宽度等。任何想法都非常感谢。

我找到了一个 VB 宏 here这将模拟事件工作表上任何合并单元格的自动调整。来源学分来自 MrExcel.com

For Each c In ActiveSheet.UsedRange
