.net MAUI Grid in ListView not spacing columns properly

Question

Im trying to make a list of items where each item has the same amount of columns containing a label. Since the text in each label is of different size I want the columns to be a percentage of the available width so they line up between the different list items. This is where I run into problems. Even tho I set the Grid column width to "*" they are not using the available width. I'm looking for a solution comparable to the WPF SharedSizeGroup.

tldr: ListView in .net MAUI with evenly spaced columns across the list items.

<ListView ItemsSource="{Binding TransactionViewmodels}" Grid.Row="1">
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <Grid ColumnSpacing="24" Margin="24">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    
                    <Label Grid.Column="0"

Answer 1

I was able to reproduce the error assuming you have your list inside a Grid with a columnDefinition Auto:

Without modifying your xaml, all I did was assign the column definition to * and it looks like this:

I'm guessing your problem is somehow related to the ListView container and not the itemTemplate
