Bug report

in mpl.css we have:

table.docutils th {
    [...]
    width: 100px;
}

which causes problems for some tables, e.g. here

Note: This only happens on Firefox, not on Safari/Chrome/Edge.

The width limit came in via #2184. (ping @NelleV?)

I suppose it could be removed - anyway imposing a fixed width on basically all <th> does not seem reasonable. AFAICS there is almost no effect. The only difference I found is that the table in the loc parameter in https://matplotlib.org/3.3.3/api/_as_gen/matplotlib.axes.Axes.legend.html#matplotlib.axes.Axes.legend wraps it's header:

with width:

without width:

Required Actions:

1. Remove the width parameter.
2. Find out why the legend loc table header wraps and add some CSS to prevent that.
