Grid Header Length issue

Hi, I have a problem with grid header length.
When I use “adjust”(true or header) property with html content in header cell,
Header width seems the size of html code, not DOM’s width size.

please tell me how to fix it.
Thanks.

Please, try to set htmlEnable:true for that column with the checkbox in the header.
