研究方向
Investigate the unterminated regular expression error at line 520 of the react spreadsheet grid bundle file (node modules/react spreadsheet grid/lib/bundle.js). The issue is caused by a broken regex in a line that adds sourcemap comment. Consider fixing the regex by properly escaping the expression or updating the dependency to a newer version. If the fix is simple, open a PR to patch the library or suggest a workaround like using a different bundler version.
