I was able to generate a word document report having a simple table using R markdown but I was not able to generate the report with table having grids.
I tried to create a reproducible code.

title: "Unable to create table having grids"
output: word_document

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## R Markdown simple table
Tables Are Cool
------------- ----------- -----------
col 3 is right-aligned $1600
col 2 is centered $12
zebra stripes are neat $1"
## Table Does Not have grids in it.
