Subject: [PATCH 1/2] Enhance table rendering and string handling for East
 Asian characters

- Updated table.dart to use displayWidth for accurate column width calculation.
- Modified pubspec.yaml to clean up dependency version formatting.
- Added tests in string_test.dart for East Asian character display width and text wrapping.
- Introduced a new test in table_test.dart to validate table rendering with East Asian characters.
