Hi @LevelbossMike, this is great, but I have two questions:
- I think your code creates thead > th -- but I think the "technically correct" thead looks like thead > tr > th . This could cause confusion if someone uses the selector 'tr' and expects to only get the non-header rows, but you prevent this by using the nested selection d3.select('tbody').selectAll('tr') -- which excludes header rows.
- You enter() your headers (th) using d3.keys() and your cells (td) using d3.values() -- but both of those say "order of the returned array is undefined", which means the headers could appear in a different order than the values. Right?
