Hey - I've left some high level feedback:
- The null checks in
executeanddisposeonly guard againstnull, butData.get(id)is likely to returnundefinedwhen missing; consider using a broader check (e.g.,if (!univerSheet) return;) to avoid runtime errors in that case. - In
dispose, you callData.remove(id)before verifying thatuniverSheetexists; consider performing the existence check first so that you only remove entries you actually retrieved.

## Overall Comments
- The null checks in `execute` and `dispose` only guard against `null`, but `Data.get(id)` is likely to return `undefined` when missing; consider using a broader check (e.g., `if (!univerSheet) return;`) to avoid runtime errors in that case.
- In `dispose`, you call `Data.remove(id)` before verifying that `univerSheet` exists; consider performing the existence check first so that you only remove entries you actually retrieved.Help me be more useful! Please click 👍 or 👎 on each comment and I'll use the feedback to improve your reviews.
