Tabulator (Align and Sort)

Hello everyone,

I love tabulator, for me it is the widget that was missing !!! Very happy.
Quick question: I am having a hard time trying to find out how to align the columns, they are all left aligned, but I’d like to center some and right align some numbers. What did I miss?

Another tabulator related: can I hide the sorting arrow on column headings?

Thanks,
TM
