Describe the new feature being added
Implement a fill handle

How will this feature improve this extension
There may be times when you need to copy the content of one cell to several other cells in your data table. You could copy and paste the content into each cell, but this method would be time-consuming. Instead, you can use the fill handle to quickly copy and paste content to adjacent cells in the same row or column.
