Review Comment:
This change covers the opening statement in my Jira but not the complexity
described in my follow-up statement.
I believe the code should check to see if givenRowClass matches
`"\b(?:a|b)\b"` and skip appending rowClass if it does. That is, don't add "a"
or "b" if the provide class already has one or the other. This would allow the
consumer to decide whether a row is initially odd or even.
Why would one want to control this? In order to create a table which
supports hiding/showing selected rows and have it initially displayed with the
rows hidden.
To be clear, the zebra striping does not work correctly when rows are
hidden. To address the matter, javascript must be employed to fix up the "a"
and "b" assignments when rows are hidden/displayed and I did not see a way to
have doxia execute some javascript just before or just after the document is
rendered.
Without this control one must first display all the rows and then hide the
rows that should be hidden. This can create a noticeable flicker. In my use
case, I opted to start with no rows hidden because of the flicker. The user
then has to select a toggle to hide the noise, but it would be better
experience to start with those rows already hidden.
