Btw, if you want to vertically align just some tables - like the
ones produced by get_feat.pl, the enclosed patch should do the
job.

PS.: It seems worth mentioning here, as others may find issues when
trying to customize the Kernel-specific CSS styles.
It took me a while to find a way for the style to be properly
applied, due to CSS Specificity[1].
[1] I don't usually deal with CSS style sheets :-)
So, had to do some research and lots of tests.
Those are two useful references about that:
https://stackoverflow.com/questions/12258596/class-overrule-when-two-classes-assigned-to-one-div
https://www.smashingmagazine.com/2007/07/css-specificity-things-you-should-know/
The thing is that the tables (tested with Sphinx 2.4.4) are created
with multiple classes:
<table class="top-aligned docutils align-default">
As the user-specified class (top-aligned) is the first one (instead of
the last one), it has less precedence than "docutils" or "align-default"
classes.
So, if one specifies at the CSS file just:
.top-aligned {
vertical-align: top;
color: red;
}
The table color will change to red as expected, but the vertical-align
will be overridden by the other classes.
So, we need to place all classes there, in order to increase
the CSS Specificity:
table.top-aligned.docutils.align-default td {
vertical-align: top;
}
Thanks,
Mauro
[PATCH] scripts: get_feat.pl: align tables vertically on top
In order to make the full features tables, align
them on the top.
