Drag & Drop

FlexSheet supports drag and drop the columns or rows into other columns or rows.
FlexSheet does not only copy or move the data of the cells, but also copy or move the style of the cells.
When drag drop without any key pressing, it will move the selected columns or rows into the dropping columns or rows.
When drag drop with 'Ctrl' key pressing, it will copy the selected columns or rows into the dropping columns or rows.
When drag drop with 'Shift' key pressing, it will change the position of the selected columns or rows with the dropping columns or rows.
