insert section with page_margins, header and footer

[zq2323]

Hi there, when I tested the example of the [insert-sections], I encountered two issues.

---
output: 
  officedown::rdocx_document:
    page_margins:
        top: 1.29
        bottom: 0.67
        left: 1.1
        right: 0.79
        header: 1.29
        footer: 0.67
        gutter: 0
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(officedown)
library(officer)
library(flextable)
\```

```{r}
qflextable(head(mtcars))
\```

```{r}
block_section(
  prop_section(
    page_size = page_size(orient = "landscape"),
    type = "continuous",
    page_margins = page_mar(top = 1.29, bottom = 0.67, left = 1.1, right = 0.79, header = 1.29, footer = 0.67, gutter = 0),
    header_default = block_list(fpar(ftext("mtcars header"))),
    footer_default = block_list(fpar(ftext("mtcars footer")))
  )
)

• how can I align the page margins in the YAML, which one below is correct?:

I tried to set the page margins in the yaml, but the header in the last blank page is not expected.

the second page is what I want:

• I also want to have your help about how can I remove the last blank page since I didn't write down any words after the section.
