How to make TableView fit to content, with no extra rows

When rendering a TableView, on either Android or iOS, it takes up a certain amount of space, regardless of the size of the content. My sample code is the following XAML:

<TableView>
    <TableSection>
        <TextCell Text="Cell 1" />
        <TextCell Text="Cell 2" />
        <TextCell Text="Cell 3" />
    </TableSection>
</TableView>

On iOS, it takes up a screen height and is filled with blank empty rows after the 3 real ones. And on android it's something like half a screen.

How do I make it fit to the size of the content and only show the 3 rows it has?
