The tallest cell in a row determines the height of all cells in the row.

一行中最高的单元格确定该行中所有单元格的高度。

So, for example, when the text of a cell is changed, the corresponding row height is invalidated .

因此，举例来说，当一个单元格的文本改变，相应的行高度失效。

This raises the question how these ICONS would align vertically if they were in cells that wrapped to multiple lines OR were in rows with greater than needed row height.

这提出了另外一个问题，如果多行单元格合并了或者行高大于所需行高的话，图标将如何竖直对齐呢？
