TVirtualTable component is TDataSet descendant. It represents an in-memory data storage that does not have linked data files. Immediately after creating a virtual table will be empty.To add fields to the virtual table, call AddField method. Then you define new fields or load existing table files so that virtual table object becomes initialized and ready to be opened.

When you close the virtual table, it will discard its record set. To keep data you entered at design-time for later use you may wish to include voStored option in the Options property. At run-time you need to call SaveToFile method explicitly to store modifications to the file that may be retrieved back into the virtual table by calling LoadFromFile method later.

Key features:

• Free of charge binaries
• Represents an in-memory dataset
• Can store record data in the file (at run-time) and in dfm (at design-time)
• Provides expanded ability for locating records
• Supports records filtering
• Local sorting ability by several fields
• Allows to add and remove fields to the existing data
• Optimized string and row data storing
• Advanced design-time editors
• Available source code by registration
