ListView不适用于列。您应该使用CommunityToolkitDataGrid。

<toolkit:DataGrid
    AutoGenerateColumns="False"
    ItemsSource="{x:Bind ViewModel.ItemsOC, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
    <toolkit:DataGrid.Columns>
        <toolkit:DataGridTemplateColumn
            Width="*"
            Header="*">
            <toolkit:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <StackPanel>
                        <Border
                            HorizontalAlignment="Left"
                            Background="Orange"
                            CornerRadius="8">
                            <TextBlock
                                Margin="0,1,6,3"
                                FontSize="10"
                                FontWeight="SemiBold"
                                Foreground="#000"
                                Text="{Binding Data_0}" />
                        </Border>
                    </StackPanel>
                </DataTemplate>
            </toolkit:DataGridTemplateColumn.CellTemplate>
        </toolkit:DataGridTemplateColumn>
        <toolkit:DataGridTextColumn
            Width="70"
            Binding="{Binding Data_1}"
            Header="70" />
        <toolkit:DataGridTextColumn
            Width="70"
            Binding="{Binding Data_2}"
            Header="70" />
        <toolkit:DataGridTextColumn
            Width="70"
            Binding="{Binding Data_3}"
            Header="70" />
    </toolkit:DataGrid.Columns>
</toolkit:DataGrid>
