Handle col/rowspans in mediawiki tables

[Dolu89]

Hello,
I discovered a problem on the converter mediawiki to gfm (and all markdown destination)
It cuts off everything after the colspan
Pandoc version (ubuntu 20.04 LTS)

pandoc 2.5
Compiled with pandoc-types 1.17.5.4, texmath 0.11.2.2, skylighting 0.7.7

Source mediawiki

Block template creation can be influenced by various parameters:
{| class="wikitable"
!colspan=4|template request
|-
! Key !! Required !! Type !! Description
|-
| capabilities || No || Array of Strings || SHOULD contain a list of the following, to indicate client-side support: [[#Optional: Long Polling|"longpoll"]], "coinbasetxn", "coinbasevalue", [[bip-0023.mediawiki#Block Proposal|"proposal"]], [[bip-0023.mediawiki#Logical Services|"serverlist"]], "workid", and any of the [[bip-0023.mediawiki#Mutations|mutations]]
|-
| mode || No || String || MUST be "template" or omitted
|}

Result of mediawiki

I run this command to transform my mediawiki file to a md file
pandoc -f mediawiki -t gfm ./mediawiki-file.mediawiki -o ./gfm-file.md

Result provided by pandoc (gfm)

Block template creation can be influenced by various parameters:

| template request |
| ---------------- |
| Key              |
| capabilities     |
| mode             |

Result of gfm

Until recently pandoc could not represent col/rowspans in tables.
This has changed in the basic types, but we haven't updated all the readers and writers yet.
