mergeCells (Merge Cells)

This collection expresses all the merged cells in the sheet.

[Example:

This example shows that three ranges are merged. The formatting and content for the merged range is always stored in the top left cell.

<mergeCells>  
  <mergeCell ref="C2:F2"/>  
  <mergeCell ref="B19:C20"/>  
  <mergeCell ref="E19:G19"/>  
</mergeCells>
