To actually make the records "go away" permanently afer a DELETE command, you'd have to PACK the table. Otherwise the DELETE command just marks the records as deleted and toggling SET DELETED ON/OFF either shows or doesn't show the marked for deletion records.
DELETED but not PACKED records can be "brought back" with RECALL.
ZAP is the fastest was to remove all records.
To get an empty table with the same stucture, you can use COPY STRUCTURE TO NewTable
