# Add Virtual Column
Virtual fields (columns) can be added to the data table for display. **These virtual fields do not exist in the actual database but combine or calculate values from existing fields to present new information.** For instance, you can create a 'Full Name' column by combining 'First Name' and 'Last Name,' or generate a 'Total Amount' column by multiplying 'Quantity' and 'Unit Price.' This feature allows users to flexibly display and analyze necessary information without altering the original data.
