order by Table Number Field % set entriesList = craft.entries.section('parks').relatedTo(entry.Line.one()).all %}

Every Element has a Table where a Number is set
I want to order it by the Number. How can i do it? 

Thanks
orderBy() should do the trick.
The docs show following syntax: .orderBy('elements.dateCreated asc')

Maybe something like:

{% set entriesList = craft.entries.section('parks')
   .relatedTo(entry.Line.one())
   .orderBy('elements.tableName.row(n).columnName asc')
   .all
%}
