If enableAutoFill is set to true, then the autofill icon will be displayed on cell selection to copy cells.

It requires the selection mode to be Cell, cellSelectionMode to be Box and also Batch Editing should be enabled.

Limitations of AutoFill

Since the string values are not parsed to number and date type, so when the selected string type cells are dragged to number type cells then it will display as NaN. For date type cells, when the selected string type cells are dragged to date type cells then it will display as an empty cell.
Linear series and the sequential data generations are not supported in this autofill feature.

Paste

You can able to copy the content of a cell or a group of cells by selecting the cells and pressing Ctrl + C shortcut key and paste it to another set of cells by selecting the cells and pressing Ctrl + V shortcut key.
