This change does not limit the number of split rows a user can put into +a table; it only restricts the number of split tables to one. + +*Impact:* To prevent breaking existing visualizations, saved objects containing nested table splits will be automatically +migrated to contain only one split table, converting any existing split tables beyond the first to split rows. No action +should be required as a result of this change, but be aware that users with saved data table visualizations that contain +multiple split tables will now see those tables rendered differently.
