'repeat' copying
The sample shows behavior of the 'repeat' clipboard (clipboard:'repeat'), which can be characterized as follows:
1) When the copy area is less than the one selected, copied cells are repeated a specific number of times to fill the selected cells.
2) When the copy area is greater than the one selected, copied cells fill only the selected area and don't 'touch' the cells nearby.
Use ctrl+c and ctrl+v to copy and paste content.
