你好，慧勤 陈，感谢联系社区！
是的，在合并时只保留左上角数据。
若是希望合并单元并且显示所有原本单元格的数据：
建议选中需要合并的内容（图上是3行“啊”），
按下Ctrl+C（复制），
然后点击工具栏上的“开始”，左侧“剪切板”右边的小箭头，将打开剪切板。
然后点击“合并后居中”，此时只显示了一行数据的内容。
然后点击表格上面的输入框，出现插入光标并选中所有内容。
然后点击剪切板中复制的文字，将粘贴所有内容到单元格内。
关于合并后如何换行，
可以按下 Alt+Enter（回车键）。
若是有任何疑问，请随时回复。

Hello,
Welcomer to the Mircosort Community.
Yes, only the top-left corner data is retained when merging.
If you want to merge cells and display data from all original cells:
It is recommended to select the content that needs to be merged (the figure is 3 lines of "啊"),
Ctrl+C (Copy),
Then click "Start" on the toolbar, and open the shear plate.
Then click "Center after Merge" and only one row of data is displayed.
Then click the input box above the table to appear the insert cursor and select everything.
Then click on the copied text in the clipboard to paste everything into the cell.
About how to wrap a line.
You can press Alt+Enter.
If you have any questions, please feel free to reply.
Kind Regards,
