Constructing rtables Manually

In rtables: Reporting Tables

## Overview

The main functions currently associated with `rtable`s are

Tables in `rtables` can be constructed via the layout or `rtabulate`
tabulation frameworks or also manually. Currently manual table
construction is the only way to define column spans. The main
functions for manual table constructions are:

* `rtable()`: collection of `rrow()` objects, column header and
  default format
* `rrow()`: collection of `rcell()` objects and default format
* `rcell()`: collection of data objects and cell format

## Simple Example


```r
library(rtables)

tbl <- rtable(
  header = c("Treatement\nN=100", "Comparison\nN=300"),
  format = "xx (xx.xx%)",
  rrow("A", c(104, .2), c(100, .4)),
  rrow("B", c(23, .4), c(43, .5)),
  rrow(),
  rrow("this is a very long section header"),
  rrow("estimate", rcell(55.23, "xx.xx", colspan = 2)),
  rrow("95% CI", indent = 1, rcell(c(44.8, 67.4), format = "(xx.x, xx.x)", colspan = 2))
)

Before we go into explaining the individual components used to create this table we continue with the html conversion of the rtable() object:

as_html(tbl, width = "80%")

Next, the [ operator lets you access the cell content.

tbl[1, 1]

and to format that cell run format_rcell(tbl[1,1])=r #format_rcell(tbl[1,1]).

Note that tbl[6, 1] and tbl[6, 2] display both the same rcell because of the colspan.
