@kktheballer: Please review, and for future contributions, please ensure to use spaces instead of tabs.

[kktheballer]

@jleveque Thank you so much for looking into the formatting and for making the changes. I will make sure to use spaces and watch out for unecessary whitespaces from now on.

I believe one of the checks has failed. Let me try and rerun that first.

[kktheballer]

retest this please

[jleveque]

@kktheballer: Looking at the test failure, it appears that there is no V6 info in the output, but it is expected. Do you have an idea why?

[kktheballer]

@jleveque Let me take a look. Oddly, the errors I see after retest look different from the errors I saw in the original errors of this #1211 PR.

(In the original PR everything was passing.. Looking into)

[kktheballer]

retest this please

the unit tests failed. likely due to the refactoring.

the unit tests failed. likely due to the refactoring.

That's my assumption, also. @kktheballer: Can you please review my changes, and check if I over- or under-indented a section?

[kktheballer]

@jleveque Thanks for the indentation fix commit. Yes, it appeared that the issue was with the indentation level at which the table was finally displaying values.

Will keep in mind about the formatting for next time.
