8 One of the most annoying features of bootstrap and/or the (informal)
9 [[bootstrap theme|todo/merge_bootstrap_branch/]] is the lack of styling on tables. It makes
10 tables look horrible! Look, for example, as the table in [this
11 page](https://web.archive.org/web/20180513200625/https://anarc.at/blog/2018-04-12-terminal-emulators-1/): margins are tiny so everything is jumbled up together, and
12 there are very little visual markers to differenciate between cells. I
13 don't have a better example handy, but this is particularly bad when a
14 cell ends up having long lines of text that are wrapped with multiple
17 Bootstrap has a nice [table](https://getbootstrap.com/docs/4.0/content/tables/) style that is not automatically
18 applied to all tables, probably to avoid breaking table-based layout
19 and other custom controls like calendars a random site might spew
20 out. Unfortunately, the various Ikiwiki output plugins (most notably
21 the [[plugins/mdwn]] plugin) do not add that class to generated
26 I found there are two ways of fixing that. One is to use raw HTML: the
27 [[plugins/htmlscrubber]] plugin will let through `class` elements in
28 tables so this will actually work:
30 <table class="table"><tr><td>This<td>is<tr>a<tr>table!</table>
32 But of course, it would be nice if Markdown-formatted tables would
33 actually render correctly as well. For this, I have written a [simple
34 plugin](https://gitlab.com/anarcat/ikiwiki/blob/bootstrap/IkiWiki/Plugin/bootstrap.pm) that adds that class to empty table tags. It's very dumb, but
35 it should generally work, or at least it works for my case. It will
36 not touch any `<table>` tag that already has other class elements, so
37 it should be safe to use alongside other plugins that generate their
38 own `<table>` markup, provided they *do* add some sort of `class`,
39 `id` or other attribute. Unfortunately, the [[plugins/contrib/bibtex]]
40 plugin does not do that correctly and somewhat looks ugly with this
41 plugin. Compare for example, [this old version](https://web.archive.org/web/20170717065911/https://anarc.at/communication/) with [the new
42 rendering](https://web.archive.org/web/20180626203321/https://anarc.at/communication/). I'm still unsure which one looks better, actually...
46 Anyways, I wasn't quite sure where to put this, but it seems like an
47 important improvement to make if we're going to
48 [[todo/merge_bootstrap_branch]]. I am not sure of the implementation
49 at all: the best way I found to edit only the rendered content (and
50 not the whole HTML page with the template) is to use the `sanitize`
51 hook, but I'm not sure it's the right way to go. It certainly seems
52 backwards to introduce new markup in a "sanitization"
53 procedure. Furthermore, I first tried to change *all* `<table>` tags
54 even if they had extra attributes, but I found I didn't want to add
55 `class` attributes to elements that already had some, soand that ended
56 up making the regex work way too messy, so I stuck to the simpler
59 Furthermore, there might be other markup elements we want to improve
60 upon. This only fixes tables, but maybe other elements would benefit
61 from additionnal styling. The [content](https://getbootstrap.com/docs/4.0/content/reboot/) section of the bootstrap
62 docs says there are special classes for tags like `img`, `form`,
63 `input` and `div` that might be interesting to look at...
