You can have up to 500 data tables in your project. Each data table can contain:
•Any number of rows (limited by RAM and hard disk space). We've tested hundreds of thousands of rows.
•Up to 256 data set columns. Prism 5 only allowed 104.
•Up to 256 subcolumns. Prism 5 only allowed 52.
If your table has more columns or subcolumns that Prism 5 can handle, the table will simply not be included when you open the file in Prism 5.
