Pandoc转换Markdown至Word时如何统一设置字体与字号？

Great question! The reason your mainfont settings aren't working is that those parameters are designed for LaTeX/PDF output, not DOCX. Pandoc handles DOCX formatting differently—it relies on Word's built-in styles rather than LaTeX-style font variables. Let's walk through two reliable ways to set a universal font and size for your document:

Method 1: Use a Custom Reference DOCX Template (Most Intuitive & Controllable) #

This is Pandoc's recommended approach for consistent DOCX formatting, as it lets you fully control every style:

1. Export Pandoc's default reference template
   Run this command in your terminal to generate a base Word template that matches Pandoc's default styling:

   pandoc -o reference.docx --print-default-data-file reference.docx
   

2. Modify the template's styles
   Open the generated reference.docx in Word 2016, then use the Styles panel (click the small arrow in the bottom-right corner of the "Styles" group under the "Home" tab):
   • Locate all styles used in your document: "Normal" (body text), "Heading 1" through "Heading 6", "List Paragraph", "Block Quote", etc.
   • Right-click each style, select Modify, then set the font to Arial/Palatino, adjust the font size, and check "New documents based on this template" before saving the change.
   • Make sure to update every style you want to standardize—Pandoc maps Markdown elements directly to these Word styles.
3. Convert with your custom template
   When converting your Markdown file, specify your modified template with the --reference-doc flag:

   pandoc your-document.md -o output.docx --reference-doc=reference.docx
   

Method 2: Quick Fix with a Lua Filter (For Batch Adjustments) #

If you want a lightweight alternative without modifying a template, you can use a simple Lua filter to enforce font settings across all text elements:

1. Create a file named set-universal-font.lua with this code:

   -- Apply target font to all paragraph text
   function Para(el)
     el.attributes["font-family"] = "Arial"
     return el
   end
   -- Apply target font to headings
   function Header(el)
     el.attributes["font-family"] = "Arial"
     return el
   end
   -- Add more element types (like lists, quotes) if needed
   

2. Run the conversion with the filter:

   pandoc your-document.md -o output.docx --lua-filter=set-universal-font.lua
   

   Note: This method is less comprehensive than using a template, as Word's built-in styles may override some settings. Sticking with the reference template is better for long-term consistency.

Why Your Previous Attempts Failed #

Just to clarify: The mainfont YAML setting and --variable mainfont command-line parameter only work when generating PDFs via LaTeX. They have no effect on DOCX output, which is why those changes didn't show up in your Word files.
