%% defvals is a list of {Col, Defval}, ordered by column
%% number
+%% [{Col :: integer(), Defval :: term()}]
%% status_col is an integer
+%% pos_integer()
%% not_accessible a sorted list of columns (> first_accessible)
%% that are 'not-accessible'
-%% indextypes is a list of #asn1_type for the index-columns,
-%% ordered by column number
-%% first_accessible is an integer, the first non-accessible
-%% column
+%% [pos_integer()]
+%% index_types is a list of #asn1_type for the index-columns,
+%% ordered by column number or an "augment"-tuple
+%% [asn1_type()]
+%% first_accessible is an integer, the first accessible column
+%% pos_integer()
%% first_own_index is an integer. 0 if there is no such index for
%% this table.
%% This is not the same as the last integer in the oid!
%% Example: If a table has one own index (oid.1), one
%% column (oid.2) and one imported index then
%% first_own_index will be 2.
+%% non_neg_integer()
+%% For a augmented table, it will instead look like this:

+%% nbr_of_cols pos_integer()
+%% not_accessible [pos_integer()]
+%% first_accessible pos_integer()
