研究方向
The issue is caused by exceljs using new Function() which is blocked by CSP. The contributor should locate the source code that triggers this eval (likely in declare.js or similar). Investigate if there is a build time option to remove eval or use a safer alternative. Review the library's webpack configuration and consider adding a CSP compatible build.
