Flextables output doesn't appear without chunk option echo = TRUE

[thealk]

flextable() output appears to only show up in resulting .docx outputs if the chunk option is set to echo = TRUE. This is problematic for any sort of writing projects where the code needs to be hidden (e.g., scientific manuscripts). The same code renders acceptably using word_document. The flextable package is extremely useful for use with .docx outputs/collaborators and plays nice with the captioner package for cross-referencing in lieu of using bookdown::word_document2, so would be wonderful if supported (it may be supported already and I am just missing something).

Rmarkdown code

---
title: "Testing flextable behavior in redoc"
output:
  redoc::redoc: default
  word_document: default
---

`​``{r setup​}
library(flextable)
```

## Test

The following table won't show up in redoc:

```{r echoF, echo=FALSE}
flextable(head(cars))
```

But the next table will:

```{r echoT, echo=TRUE}
flextable(tail(cars))
```

Output

rendered_redoc.docx
rendered_word_document.docx

Please take a moment and consider if the issue is actually in knitr,
rmarkdown, officer or pandoc. Thanks!

Same problem, following

[albert-ying]

I get it work by using inline code to print the table

library(magrittr)
library(flextable)

tab_1_curr <- structure(list(myRegion = c("a", "b", "c", "BRITISH COLUMBIA"
 ), Current_Perc_1 = c(85.9, 90.8, 89.7, 88.4), Current_Perc_2 = c(88, 
 91, 89, 89.3), curr_change_1_to_2 = c(2.09999999999999, 0.200000000000003, 
 -0.700000000000003, 0.9)), .Names = c("myRegion", "Current_Perc_1", 
 "Current_Perc_2", "curr_change_1_to_2"), row.names = c(NA, 4L
 ), class = "data.frame")


rt = regulartable(tab_1_curr) %>% 
  bold(i = ~ myRegion %in% "BRITISH COLUMBIA") %>% 
  theme_zebra() %>% 
  autofit()

`r rt`
