There's a reason people don't like to write HTML tables, 
and it's because they don't write good HTML in the first place.

Case in point, taken from a spec I'm editting right this moment:

```html
    <table id="distinguishable-table" class="matrix data complex">
        <tr>
            <th class="corner"></th>
                <th><div>
                    <span>boolean</span>
            </div></th>
                <th><div>
                    <span>numeric types</span>
            </div></th>
                <th><div>
                    <span>bigint</span>
            </div></th>
                <th><div>
                    <span>string types</span>
            </div></th>
                <th><div>
                    <span>object</span>
            </div></th>
                <th><div>
                    <span>symbol</span>
            </div></th>
                <th><div>
                    <span>interface-like</span>
                </div></th>
                <th><div>
                    <span>callback function</span>
            </div></th>
                <th><div>
                    <span>dictionary-like</span>
            </div></th>
                <th><div>
                    <span>sequence-like</span>
            </div></th>
        </tr>
        ...
    </table>
```

I don't know how this got into the state it's in, but that's *awful*.
It's a heading row not in `thead`,
the tags are broken into newlines in an arbitrary pattern,
and the indentation is just *the worst*, totally self-inconsistent and wrong.

(The `div` and `span` are just some styling wrappers to enable a neat diagonal layout;
they're not the point of the complaints here.)

Here it is fixed:

```html
    <table id="distinguishable-table" class="matrix data complex">
        <thead>
            <tr>
                <th class="corner"></th>
                <th><div><span>boolean</span></div>
                <th><div><span>numeric types</span></div>
                <th><div><span>bigint</span></div>
                <th><div><span>string types</span></div>
                <th><div><span>object</span></div>
                <th><div><span>symbol</span></div>
                <th><div><span>interface-like</span></div>
                <th><div><span>callback function</span></div>
                <th><div><span>dictionary-like</span></div>
                <th><div><span>sequence-like</span></div>
        </thead>
        ...
    </table>
````

Everything rolled up into single reasonable lines,
omittable end tags omitted,
`thead` added...
it's a beautiful thing now.

(Technically the `</thead>` could be omitted
since it'll be implied when the parser sees the following `<tbody>` start tag,
but I prefer keeping it in
so I can rely on automatic `tbody` insertion instead,
which lets me reduce the indentation of the body rows by one level.)
