typst: table colspan not supported

[pzeinlinger]

The latex writer does not support the colspan attribute.

Minimal example available here https://pandoc.org/try/?params=%7B%22text%22%3A%22%3Ctable%3E%5Cn%3Cthead%3E%5Cn%3Ctr+class%3D%5C%22header%5C%22%3E%5Cn%3Cth%3E%3Cp%3E1%3C%2Fp%3E%3C%2Fth%3E%5Cn%3Cth%3E%3Cp%3E2%3C%2Fp%3E%3C%2Fth%3E%5Cn%3Cth%3E%3Cp%3E3%3C%2Fp%3E%3C%2Fth%3E%5Cn%3Cth%3E%3Cp%3E4%3C%2Fp%3E%3C%2Fth%3E%5Cn%3C%2Ftr%3E%5Cn%3C%2Fthead%3E%5Cn%3Ctbody%3E%5Cn%3Ctr%3E%5Cn%3Ctd+colspan%3D%5C%224%5C%22%3EColumn+1-4%3C%2Ftd%3E%5Cn%3C%2Ftr%3E%5Cn%3C%2Ftbody%3E%5Cn%3C%2Ftable%3E%5Cn%22%2C%22to%22%3A%22typst%22%2C%22from%22%3A%22html%22%2C%22standalone%22%3Afalse%2C%22embed-resources%22%3Afalse%2C%22table-of-contents%22%3Afalse%2C%22number-sections%22%3Afalse%2C%22citeproc%22%3Afalse%2C%22html-math-method%22%3A%22plain%22%2C%22wrap%22%3A%22auto%22%2C%22highlight-style%22%3Anull%2C%22files%22%3A%7B%7D%2C%22template%22%3Anull%7D

Typst has had support for col spanning cells with the external tablex package for some time now and has recently included it into the standard table as well https://github.com/typst/typst/pull/3239.

That change is not yet in any released version. When it is released, we can try to support it. The LaTeX writer can support colspans, but the typst parser does not recognize them since there is still no official support for them.

Typst v0.11 has recently been released: https://github.com/typst/typst/releases/tag/v0.11.0 Support for colspans is now natively available.

I've already added commits that support colspans and rowspans for typst (both input and output). It's not yet in a released version of pandoc but it will be in the next release. So, closing this.
