I am trying to make a Spreedsheet program like MsExcel, but when i insert a table with a lot rows and colums (500, 500) the program uses more than 200 mb of RAM memory. What can i do to fix that ?

I doubt that this table occupies all that memory, but in any case, unlike spreadsheet application, TRichView allocates memory for each table cell, and this memory cannot be reduced significantly.
