caption in flextable comes in theprevious page + no toc printed in R word markdown

Question

Below is a basic reproductive example of my.rmd to create a word output in R.
I need help with fixing:
1-the newDoc.docx shows no table of contents
are toc: true in YAML and #headig , ## heading , .. not enough to make toc?
2-table is printed in one page while its caption is printed in the previous page
This does not happen when my table is as small as in this example, but in my actual multipage table this happens.
3-can I add continued to the top my multipage table right from R for flextable
similar to longtable= T in kableextra

title: "test"
output: 
        word_document:
         toc: true

             footnote(i = 1, j = 1,
                            value = as_paragraph(c("This is my footnote.")),
                            ref_symbols = c("i"),
                            part = "header")

#add flextable to the templabe
doc <- doc %>%
                 body_add_flextable(table, split = T )

#save template as a new .docx
print(doc, target = "newDoc.docx")
