Quadrillions of rows and columns

Both rows and columns are virtualized in this grid solution, so you can theoretically have up to Number.MAX_SAFE_INTEGER (about 9 quadrillion) rows and columns. Not only are the row and columns virtualized, but you can drag columns/rows to reposition them without affecting the underlying model, effectively allowing quadrillions of rows and columns that can be moved around. Here is an example using MockGridModel that displays quadrillions of rows/columns. You can:

• scroll around using the mouse or keyboard
• edit by double clicking on a value or by typing
• move columns or rows by dragging the headers.
