as slotted node












3















I have defined a shadow template as follows:



  <table id="overviewbox-loadingbox">

    <thead>

        <tr>

        <slot name="table-header"></slot>

        </tr>

    </thead>

    <tbody>

        <div id="loadingbox"></div>

    </tbody>

  </table>


The users are supposed to supply their own <th>s by something like:



  <th slot="table-header" data-column_name="description">describing here</th>


However this doesn't work. As soon as I change <th> to <span>, with all other things unchanged, the slotted node shows up. Is this because there is some undocumented quirks about using <th> and <slot> together? Thanks.

<tr> and <tbody> have a very limited set of allowed children. So you may not be able to do what you are trying to do the way you are trying to do it.



But...



You can use <div> and <span> and just set their CSS to be:



display: table-row-group;

display: table-header-group;

display: table-footer-group;

display: table-row;

display: table-cell;

display: table-column-group;

display: table-column;


Then there is no limitation of children.




You can also use the newer Customized built-in elements paradigm like <td is="my-td"></td>:

  • If you use <div> and <span> instead of <table>, <tbody>, <thead>, etc. then you can place <slot> in your code. But then you have to be careful to not allow <tr>, <td>, etc in the children that will end up in the <slot>

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
