The numbering options are set in the table management options :

  • If the numbering option you've chosen is ''Free'', you can write whatever you like, the marker will take this character string.
  • If the numbering option chosen is ''1,2,3'', you can only enter digits. They don't have to follow each other.
  • If the numbering option you have chosen is ''A,B,C'', you can enter only one letter. They do not have to follow alphabetical order.
  • If the numbering option chosen is ''A1,A2,A3'', you can enter a 2-character string. Incrementing will take place from 1 to 1. However, if you enter B1 during the process, incrementation will no longer follow this new letter. You'll have to manually enter B2, then B3 etc...

Between each extraction selection, you can activate or deactivate filters or change the type of selection.

As you make selections, you can reposition markers and the table.
