Steps to Reproduce

1. import the file with Chrome

Current Result

sometimes Chrome shows "page unresponsive" dialog

Expected Result

Chrome can render it correctly

Debug Information

• firefox doesn't have this problem
• The root cause is 262k CSS rules
  
• the file contains 65530 row *4 CSS rule = 262120

Workaround

• use default row height or reduce data row number. Create a new sheet and copy all non-blank cells from the original sheet into the new sheet.
• Increase column width to display a text completely. Disable wrap text to avoid auto height. Because wrap text will auto increase the height to produce a non-default height.
