Number
A Number column stores numeric values per row — for example quantity, price, or score. In addition to the standard options (Name and Private), you can set a Prefix and Suffix so that values are displayed with text before or after the number (e.g. currency symbol, unit).
New column form
When you add a Number column, you configure it in the New column modal.

Name
The Name of the column — this is the label shown in the table header. For example: "Quantity", "Price", "Score".
Prefix
Optional text shown before the number in each cell. For example: a currency symbol ("$", "€"), "~", or "ca. ". The prefix is displayed in the table next to the value.
Suffix
Optional text shown after the number in each cell. For example: a unit (" kg", " m²", " %") or " pcs". The suffix is displayed in the table next to the value.
Private
When Private is on, the column is visible and editable only for selected users and groups. You define who can view and edit the column. Other users will not see or edit this column.
