I would be tempted to implement such a table in fpspreadsheet, but its
problem is that it occupies memory for empty cells while the AVLTree
stores only existing cells (at the expense of the cell record which
contains row and column indexes).
What about a two dimensional array of integers pointing to a one
dimensional array of strings, and doing some garbage collection cells
are set to empty strings ? (Maybe even identical strings can be managed...)
