The property - Count, which is set by the program, is the number of data entries in the TextColumns collection.

The right hand panel shows the data entries as a spreadsheet, and the properties of each data entry can be modified as required.

Some properties have a drop-down selection menu which pops-up when the property is double-clicked. Other properties are typed entries - simply click in the field to place the cursor, then type the required value.
