If the following is my setup for the default row axes, even though both axes are set to expand: true, only the first one will actually be expanded when the pivot grid loads. Maybe I am misunderstanding the point of having the name be an array of strings? the documentation doesn't seem to say what that is. Can I nest these somehow?
defaultRowAxes: PivotGridAxis[] = [
{ name: ['Branch'], expand: true},
{ name: ['Truck'], expand: true },
];
