Removing rows and columns of merged cells
When you remove a row or a column through a merged cell, every row or column that the merged cell spans is removed. It works this way when a cell or a range of cells is selected and the row or column is removed via the toolbar, the menu, the context menu or the deleteRow() / deleteColumn() methods. The context menu shows the full range in the command name, for example, Remove rows 2-4.

When whole rows or columns are selected, for example, by clicking their headers or with Shift + Space or Ctrl (Cmd) + Space, only the selected rows or columns are removed. A merged cell that spans them becomes smaller, and a merged cell left with a single cell becomes an ordinary cell.
Merged cells located below or on the right of the removed rows or columns move together with them.
