I think a custom class for the "row" could solve this. The row class should have two fields: a Map<String, Block>, where the string represents the column name and the block represents the value, and a SolrDocument. This way, we can compute the table at the end, once all column names are known, and add empty cells for rows that don’t have certain column names.
