The "show row" toggle allows you to specify whether or not you want the row numbers to be displayed along with the contents of the row. The default value for this setting is no row numbers. Turn on the display of row numbers as follows:
SQL> exec PLVtab.showrow
and then when you display the contents of a table, you will see Row N = prefixed to each row value as shown in this output from PLVtab.display :
Row 1505 = ACME Row 20200 = ArtForms
