Description

Is it possible to add feature of copying a value from a cell to other cells?

The feature can be implemented in similar way like it's implemented in Excel. In the bottom of right corner can be a small dot or square and when you hover over it, the cursor changes to a cross. Dragging the cross and highlighting other cells vertically or horizontally, the value will be copied to the highlighted cells after the cross is dropped.

Research direction
Investigate the current implementation of cell selection and mouse event handling in the DataSheet component. Look at how cells are rendered and how mouse interactions are captured. Consider implementing a drag handle on the cell corner that triggers a copy operation when dragged over adjacent cells. Review any existing drag and drop logic in the codebase for patterns to follow.
