1. Determine whether the cell is included in the merged cell. The MergeCells property can be used to determine whether a cell is included in a merged cell. For example, if A1:B2 is merged into a merged cell, then: Range("A1").MergeCells will return True!
2. Get the merged area containing the specified cells. The MergeArea property can obtain the merged area containing the specified cells, such as: A1:B2 is merged into a merged cell, then: Range("A1").MergeArea.Address will return $A$1:$B$2.
3. Merge replication. When merging cells, we often encounter that in the merged cell range, there are multiple cells with content, and when merging cells, it will prompt that only the data in the upper left corner can be retained. After the content is merged, all the content is also merged into the merged cell, you can use this custom macro to complete
