Horizontal scrolling of the data grid

Hello everyone

We apologize for poor English and elementary questions.

How can I take advantage of horizontal scrolling in a DataGrid with many columns?

I used the ColumnWidth parameter, but the screen layout is broken (Navbar becomes narrower)

This image does not use ColumnWidth

Navbar will be crushed if used

I'm sorry I can't show you because I can only put one image

ColumnWidth:unused

It may not be a proper workaround, but I set the CSS "min-width" and dealt with it.

Thank you.
