Code Review
This pull request refactors duplicated table formatting logic into a new centralized utility function formatTable. This is a good improvement for code reuse and maintainability. The changes in running_apps.dart and device.dart correctly adopt this new utility. I've found an opportunity to improve the new formatTable function for robustness and performance. Please see my detailed comment.

This is a bit hard to read. How about this?
return table.map<String>((row) {
final formatted = indices
.map<String>((int i) => row[i].padRight(widths[i]))
.followedBy(<String>[row.last])
.join();
return '$indentString$formatted';
}).toList();| <String>['Col1', 'Col2'], | ||
| <String>['Value1', 'Value2'], | ||
| ]), | ||
| <String>['Col1 • Col2', 'Value1 • Value2'], |

Is it maybe worth joining the result and verifying against the resulting formatted string? Visually, it'll be easier to tell that the formatting is correct:
const expected = '''
Col1 • Col2
Value1 • Value2
''';
expect(
formatTable(<List<String>>[
<String>['Col1', 'Col2'],
<String>['Value1', 'Value2'],
]).join(Platform.lineTerminator),
expected,
);
