Hi All: I just added checkbox to the header, and the header height was set to 70…via an added element style

        var columnData = [
            { id:"checkbox", header:{ content:"masterCheckbox" }, checkValue:"on", uncheckValue:"off", template:"{common.checkbox()}", width:40 },
            { id:resultData.columns[0].id,	header:[resultData.columns[0].header, null],  width:resultData.columns[0].width,	sort:resultData.columns[0].sort},
            { id:resultData.columns[1].id,	header:[resultData.columns[1].header, null],	width:resultData.columns[1].width,	sort:resultData.columns[1].sort, cssFormat:mark_status},...

So, how can I remove that element style to no-style, effectively removing that 70px element style?

Thank you

Not really related to the master checkbox. You have two line headers for 2nd and 3rd columns ( null as second value, but still it is defined )

If you remove second line headers - height will go back to normal one.
