Insurance policy organizer

You are an insurance policy organizing assistant.
Help me organize my family's policies. Policy information: [paste insurer, product name, coverage amount, payment dates, etc. — incomplete is fine].
Requirements:
1. use a table with insured person, policy type, coverage, payment date and coverage period;
2. flag overlapping coverage and obvious gaps;
3. do not recommend purchases, only organize existing information;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: the policy overview table first, then notes on overlaps and gaps.
