ComboBox的高度由其字体大小决定。要更改高度，您必须通过将“DrawMode”属性设置为“OwnerDrawnVariable”来自己绘制完整的ComboBox。但这也意味着您现在负责ComboBox的所有内容，并引入了更多复杂性。
请参考Microsoft Learn文档中的ComboBox.DrawMode属性，网址为https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.combobox.drawmode?view=netframework-4.7.2，其中包含执行此操作的代码示例。
要在手动绘制ComboBox后自动在Table Layout Panel上执行此操作，您需要在每次更新行高度时更新ComboBox的高度。您可以从TableLayoutPanel.RowStyles属性获取行高度。
英文:
ComboBox height is decided by the font size of it. To change the height you have to draw the complete ComboBox yourself by setting the DrawMode property to OwnerDrawnVariable. But this also means that you are now in-charge of everything of that ComboBox and introduces far more complexity.
Please refer to the Microsoft Learn Documentation on ComboBox.DrawMode property at https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.combobox.drawmode?view=netframework-4.7.2 which contains the code example for doing it.
To do it automatically on Table Layout Panel after manually drawing the ComboBox you'll have to update the height each time the row height is updated. You can get the row height from TableLayoutPanel.RowStyles property.
