Tabstop in fpar

[MalteSteinDE]

I want to use a tap stop in a word or officedown document to create in the footer text left and right align in the same line. But I don't get the tab stop running in fpar. Example:

---
output:
  officedown::rdocx_document
---

Left 	 Right

`r officer::fpar("Left 	 Right") `

Output in word:

How do I get the tabstop in fpar? I tried it also with \t or <w:tab/>
