Table issues in the demo

[RandallFlagg]

I have 2 issues while playing with the demo in this repo:

1. I am trying to sort the columns in the table. Although the click does print a message in the console it doesn't do sorting. I would also like to know how to add my custom sort.
2. I am trying to make the columns of the table fit to the content automaticlly but it doesn't matter what I try to do, if the content is too long it overlaps the column next to it.

I didn't change the code at all in the first issue.
In the second issue I changed only the data so it will be longer. no logic was changed.

Am I missing something or there is an issue in the code?
Is there documentation for this component?

Thanks
