Block adding or deleting by the number of rows in the table

An example of blocking the addition and deletion of rows by the number of rows and amount

For example, we need to prohibit adding more than 5 rows to the table. In the table formatting, we write:


f1=: setTableFormat(condition: $count > 5; blockadd: true)

count: listCount(list: $list)

list: selectList(table: $#ntn; field: 'id')

Are these blocks strong or weak?

This is a weak lock. If you want to set a strong one, it is done through a check in the action table code.
