How do I modify summaryBelow setting for sheet?

[Alexander]

Hi guys,

There is a '+' icon in the left side of the doc when you group rows. The problem is - by default it is 1 line below Summary row. There is a setting to move it 1 line up:

<sheetPr><outlinePr summaryBelow="0"/></sheetPr>

I've created saved the same doc with summaryBelow enabled and disabled. The only difference is:

<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="x14ac" xmlns:x14ac="http://schemas.microsoft.com/office/spreadsheetml/2009/9/ac"><sheetPr><outlinePr summaryBelow="0"/></sheetPr><dimension ref="A4:A27"/><sheetViews><sheetView tabSelected="1" workbookViewId="0"> ....

Is there a way to set this property in axlsx?

Here is a screenshot I made on windows:

BTW, I didn't find a way to change it in Excel for Mac :) Does anybody know where can I find it?

Thanks in advance,

Alex
