In previous versions, when you called the TableCollection.Create method to insert a new table right before or after the existing table, these tables were separate Table objects with their own parameters.
In the scope of the T758819 bug fix, the TableCollection.Create method merges the created table with the successive or preceded table and returns the resulting table.
To restore previous behavior and keep successive tables separate, set the RichEditControlCompatibility.MergeSuccessiveTables property to false as shown below:
C#DevExpress.XtraRichEdit.RichEditControlCompatibility.MergeSuccessiveTables = false;
Visual BasicDevExpress.XtraRichEdit.RichEditControlCompatibility.MergeSuccessiveTables = False
