You are presented with a list of tables in the bottom-left corner. Clicking on one of them shows you this table.

In the bottom-right you are presented with table documentation if the library designer provided this.

What data to put in a table depends on how the library designer intended the table to be used. And I recommend you read up on for example the VR basic event library to get an idea.

It is possible to export tables to 'csv' files. They will however be TAB seperated to allow the use of actual comma's in your data.
