You can manually create new tables in TABLE|IT.
After the creation of tables you can create and configure the desired fields.
If you already have data for your table in a CSV file you can use the feature Automatic creation of tables.
The explanations for the individual procedures can be found in the particular sub chapter.
For your new table you need fields where you can save your data. You create these with the TABLE|IT table manager.
Where can I find my table in Act!?
The creation and administration of tables in Act! is only possible with direct access to the main database. For that, you need administrator rights.
