Change template to loop through prefetched member list for each column, instead of making new queries.

Before

• default 165.93 ms (589 queries including 585 similar and 158 duplicates )
• DOMContentLoaded: 1.39 s

After

• default 54.87 ms (143 queries including 137 similar and 4 duplicates )
• DOMContentLoaded: 471 ms
