optimized some jsdocs and added some @typedef for better code tracing, see here

Wellformed the table's rowspan and/or colspan attributes, usage sample below:

| A                       | B   | C   | D                |
| ----------------------- | --- | --- | ---------------- |
| 1                       | 11  | 111 | 1111 {rowspan=3} |
| 2 {colspan=2 rowspan=2} | 22  | 222 | 2222             |
| 3                       | 33  | 333 | 3333             |

{border=1}

Output:

<table border="1">
  <thead>
    <tr>
      <th>A</th>
      <th>B</th>
      <th>C</th>
      <th>D</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td>11</td>
      <td>111</td>
      <td rowspan="3">1111</td>
    </tr>
    <tr>
      <td colspan="2" rowspan="2">2</td>
      <td>22</td>
    </tr>
    <tr>
      <td>3</td>
    </tr>
  </tbody>
</table>

current looking view as:

before rending as:

transform the cells B222,B2222,B33,B333,B3333 to hidden.

Hi 👋 Thanks for contributing

I must admit that the code is challenging, I do not know much about rowspan or colspan, and it has been some years since this code was written. I cannot totally grasp my own code either. The type-hinting will help, thank you for those!

If you could please answer my questions, I'll do a review soonish.

Thanks again 🙌

The rowspan and colspan are all the html standard for rending table. And this pkg was already supporting parsing and transform those as well. It's great. Just need a little bit extra modification, the definition is:

This improvement is solving the overflow cells, better for rendering. See the above notes.

A real rendered markdown table (490 rows x 3 columns) is launched here. It looks expectation and no more time spent(from the GitHub actions). Hopes it may helpful.

Hi there, feel free take a look this website https://wechatpay.im/openapi/, there were more than 790+ rendered pages with this feature. Hopes this pr may be merged. @arve0

Sorry for the delay. It's published with version 4.3.0.
