Can I use a tr (table row) for a named slot? And what happend when I use a tr as a slot's fallback content?
like this:
<x-table>
<tr slot="x-row">
<td>data</td>
<td>data</td>
</tr>
</x-table>
sample code in codepen https://codepen.io/JJia/pen/odXrWJ
A <tr> element must have a parent among <thead>, <tbody>, <tfoot> or <table> elements.
Unfortunately, these elements cannot support a Shadow DOM. See the list of elements with the attachShadow() method.
As a consequence, their first-level childs (i.e. <tr>) cannot be used with a slot attribute.
