'Blockquote Render Hook' is added in Hugo v0.132

Yeah, but our implementation requires AlertTitle and AlertSign, which were introduced in v0.134.0.

header-less table

Can you provide me with some examples? I believe it can be implemented using attributes.

Currently, if I write this markdown in Hugo, it will be converted to this HTML:

| Header A | Header B | Header C |
|:---:|:---:|:---:|
| Body A | Body B | Body C |
| Body D | Body E | Body F |
| Body G | Body H | Body I |

<table>
  <thead>
    <tr>
      <th style="text-align:center">Header A</th>
      <th style="text-align:center">Header B</th>
      <th style="text-align:center">Header C</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td style="text-align:center">Body A</td>
      <td style="text-align:center">Body B</td>
      <td style="text-align:center">Body C</td>
    </tr>
    <tr>
      <td style="text-align:center">Body D</td>
      <td style="text-align:center">Body E</td>
      <td style="text-align:center">Body F</td>
    </tr>
    <tr>
      <td style="text-align:center">Body G</td>
      <td style="text-align:center">Body H</td>
      <td style="text-align:center">Body I</td>
    </tr>
  </tbody>
</table>

But in <table>, both <thead> and <tbody> are optional. For example, this is valid HTML table without header.

<table>
  <tr>
    <td>Body A</td>
    <td>Body B</td>
    <td>Body C</td>
  </tr>
  <tr>
    <td>Body D</td>
    <td>Body E</td>
    <td>Body F</td>
  </tr>
</table>

To create this table in markdown via kramdown, for example, you have to write like this:

| Body A | Body B | Body C |
| Body D | Body E | Body F |

I think I've saw this syntax for defining text alignment, but I don't remember which parser was that.

|:----|:---:|----:|
| Body A | Body B | Body C |
| Body D | Body E | Body F |
| Body G | Body H | Body I |

These maybe in area of parser (Goldmark), not render hooks...

This feature is available since github.com/hbstack/[email protected]. Check https://hbstack.dev/docs/content/tables/#table-without-header out, but you still need to specify the header even if it's empty, to allow the parser to recognize if it's a table.

Thank you! 'Specifying empty header' isn't problem at all.
