  Hello,

  

  I’m seeing a strange white line in the header area, as shown in the picture. I even tried removing all CSS, but the same error persists. How can I fix this?

  Hi,

  Thank you for sharing the image. I can see the issue in the screenshot; however, I’m unable to reproduce it on my end—no white space appears in the header. Please refer to the following samples:

  • SpreadJS:
    
    https://jscodemine.mescius.io/share/F_d7Q33JOkmS33zBip8vwA/?defaultOpen={"OpenedFileName"%3A["%2Findex.html"%2C"%2Fpackage.json"%2C"%2Fsrc%2Fapp.js"]%2C"ActiveFile"%3A"%2Fsrc%2Fapp.js"}

  • Designer Component:
    
    https://jscodemine.mescius.io/share/Yw7CCu0nTUi-8GwonSGqKQ/?defaultOpen={"OpenedFileName"%3A["%2Findex.html"%2C"%2Fsrc%2Fapp.js"%2C"%2Fpackage.json"]%2C"ActiveFile"%3A"%2Fsrc%2Fapp.js"}

  Please try using the latest version, 18.1.3, and if the issue still persists, kindly share a minimal working sample or modify the shared one to replicate the issue. This will help me investigate it more effectively.

  Regards,
  
  Priyam
