Function add_table_column 

pub fn add_table_column(
    tx: &mut Transaction,
    draft: ColumnDraft<'_>,
) -> TabularResult<EntityId>

Stage an IfcTableColumn.

Every attribute is OPTIONAL in the schema, so a column carrying nothing is legal. A blank identifier is not: it would name a column that cannot be referenced.

Errors

Refuses a whitespace-only Identifier.
