Selected Range has vertical lines on Android but not on iOS.

[wildsurfer]

Describe the bug The bug is reproducible on the example project. To highlight problem even better I switched theme to the dark mode.

You may see some annoying vertical lines on a date range selection (see screenshot below). This is happening only on Android but not on iOS.

To reproduce

Steps to reproduce the behavior:

1. Run the example project on Android
2. Go to 'Range Selection' example
3. Select any date range

Expected behavior I expect it to work exactly as it works on iOS platform. There should be no vertical lines

Quick and dirty solution for me was to put TableCalendar into SizedBox and give it a width that is divisible by 7 without a remainder.

[wildsurfer]

Example:

LayoutBuilder(builder: (context, constraints) {
    return SizedBox(
        width: constraints.maxWidth ~/ 7 * 7,
        child: TableCalendar(),
    );
}

I made a fork to use in my project but I'm not sure if the solution is elegant enough to be merged into this library. Let me know what you think
