Tried to write an application with MAUI and got stuck on the simplest task – cannot display a 2D array.

For example:

double[,] my2dArray;
//calculate N and M
my2dArray = new double[N,M];
//populate array with data

Had read TechNet about TableView, ListView, CollectionView with examples, but still no any success. TableView shows only one column even when added several TableSection inside.

Using CollectionView I can set number of columns needed:

collectionView.ItemsLayout = new GridItemsLayout(M, ItemsLayoutOrientation.Vertical);

but cannot add any rows after it.
