How to align the formula number to the right in docx output

[Dagwbl]

I have to submit in docx format, then I encountered a problem, That is aligning the formula number to the right.
the quarto default style like this

But I want to the style like this

In native pandoc, I know we can use the --crossref and add template to YAML, but in quarto, I don't know what to do?

You can still use template with Quarto (https://quarto.org/docs/output-formats/ms-word-templates.html) and crossref is built in quarto (https://quarto.org/docs/authoring/cross-references.html#equations)

Did you try already the template ? Does the Pandoc crossref filter you used handled that differently that Quarto ?

If you could share a full reproducible example that would help

In order to achieve the right side of the formula numbers, we can use pandoc-crossref in native pandoc.
As shown in the following md

---
autoEqnLabels: true 
tableEqns: true 
eqnBlockTemplate: |
   `<w:pPr><w:tabs><w:tab w:val="center" w:leader="none" w:pos="4819" /><w:tab w:val="right" w:leader="none" w:pos="9638" /></w:tabs></w:pPr><w:r><w:tab /></w:r>`{=openxml} $$t$$ `<w:r><w:tab /></w:r>`{=openxml} $$i$$

eqnBlockInlineMath: true
equationNumberTeX: \\tag
eqnIndexTemplate: ($$i$$) 
eqnPrefixTemplate: Eq($$i$$)

# Test formula numbers alignment
[@eq:eq2]
$$
x+y=z
$${#eq:eq1}
formula 1

$$
x+y=z
$${#eq:eq2}
formula 2

$$
x+y=z
$${#eq:eq3}
formula 3

$$
x+y=z
$${#eq:eq4}

The conversion command is as follows：

pandoc -F pandoc-crossref test.md -o test.docx

Results:

We can compare with the default style of quarto.

We can use native pandoc with pandoc-crossref to implement that the formula number align to the right of the page, but this requires a series of pandoc-crossref parameters to be set.

I don't know how to set the pandoc-crossref parameters at quarto.

I tried the template, but I found that the formula did not apply a style

Oh ok, it is not the same syntax as pandoc-crossref and we don't have the feature of setting all this

autoEqnLabels: true 
tableEqns: true 
eqnBlockTemplate: |
   `<w:pPr><w:tabs><w:tab w:val="center" w:leader="none" w:pos="4819" /><w:tab w:val="right" w:leader="none" w:pos="9638" /></w:tabs></w:pPr><w:r><w:tab /></w:r>`{=openxml} $$t$$ `<w:r><w:tab /></w:r>`{=openxml} $$i$$

eqnBlockInlineMath: true
equationNumberTeX: \\tag
eqnIndexTemplate: ($$i$$) 
eqnPrefixTemplate: Eq($$i$$) 

I believe you can set

crossref: false

in the YAML metadata to deactivate cross ref mechanism from Quarto and use pandoc-crossref instead by adding to filters.

@jjallaire is this some feature we plan to make closer to pandoc-crossref ? Do we need to track this in a specific feature request ?

Thank you for the solution. I still expect quarto to implement the small detail. After all, in html or pdf, the formula numbers are aligned on the right, and I think they should be consistent.
