2. Optionally write a short description by adding some markdown.
3. You can fill the values manually. For importing tables check the Importing a table task.
1. Hover the header of the table and on the right a little arrow appears. It will open a list of actions that can be performed with the selected row/column.
2. Add columns/rows by clicking the arrow and choosing insert option. Column names are restricted, see the concept documentation of parameter tables for specifics.
1. Fill the table with the values you need. Pressing the tab key on your keyboard will jump to the next cell.
