Description

That would be very useful to have "where" in table sources:

  tables:
    tab_filtered:
      layer_id: table_source

      # Table name (required)
      table: table_source
      
      # SQL where conditions
      where: (TYPE = 'A') and (Pop > 100)

Contributor guide

Research direction
Study how table sources are parsed and how SQL queries are constructed in martin. Focus on the configuration parsing and the query builder modules. Identify where to add a 'where' field and ensure it is safely interpolated into the SQL query.
