Basics
======

The **htmlTable** package is intended for generating tables using [HTML](http://en.wikipedia.org/wiki/HTML) formatting. This format is compatible with [Markdown](http://rmarkdown.rstudio.com/) when used for HTML-output. The most basic table can easily be created by just passing a `matrix` or a `data.frame` to the `htmlTable`-function:


```r
library(htmlTable)
# A simple output
output <- matrix(1:4,
                 ncol=2,
                 dimnames = list(list("Row 1", "Row 2"),
                                 list("Column 1", "Column 2")))
htmlTable(output)
```

<table class='gmisc_table' style='border-collapse: collapse;'  id='table_4'>
	<thead>
	<tr>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey;'> </th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>Column 1</th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>Column 2</th>
	</tr>
	</thead><tbody>
	<tr>
		<td style='text-align: left;'>Row 1</td>
		<td style='text-align: center;'>1</td>
		<td style='text-align: center;'>3</td>
	</tr>
	<tr>
		<td style='border-bottom: 2px solid grey; text-align: left;'>Row 2</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>4</td>
	</tr>
	</tbody>
</table>

As of version 1.0.2 you **no longer need** to specify `results='asis'` for each `knitr` chunk.

Advanced
========

While it may be sufficient for basic tables a more advanced layout is often needed in medical publications with elements such as:

* row groups
* column spanners
* table spanners
* caption
* table footer
* zebra coloring (also know as *banding*):
  + rows
  + columns

As many journals require that a MS Word-document is submitted it is furthermore also important that the table imports correctly to a word processor, i.e. that the table doesn't only look nice in a web browser but also in the final document. The `htmlTable`-function is written for all these purposes.

**Note:** Due to GitHub CSS-styles the rows get automatically zebra-striped (in a bad way), borders get overridden and I haven't been able to figure out how to change this. See the vignette for a correct example: `vignette("general", package = "htmlTable")`

For demonstration purposes we will setup a basic matrix:


```r
mx <-
  matrix(ncol=6, nrow=8)
rownames(mx) <- paste(c("1st", "2nd",
                        "3rd",
                        paste0(4:8, "th")),
                      "row")
colnames(mx) <- paste(c("1st", "2nd",
                        "3rd", 
                        paste0(4:6, "th")),
                      "hdr")

for (nr in 1:nrow(mx)){
  for (nc in 1:ncol(mx)){
    mx[nr, nc] <-
      paste0(nr, ":", nc)
  }
}
```

Row groups
----------

The purpose of the row groups is to group variables that belong to the same group, e.g. a factored variable with more than two levels often benefit from grouping variables together.


```r
htmlTable(mx, 
          rgroup = paste("Group", LETTERS[1:3]),
          n.rgroup = c(2,4,nrow(mx) - 6))
```

We can easily mix row groups with regular variables by having an empty row group name `""`:


```r
htmlTable(mx, 
          rgroup = c(paste("Group", LETTERS[1:2]), ""),
          n.rgroup = c(2,4,nrow(mx) - 6))
```

When mixing row groups with variables without row groups we may want to omit the bold formatting of the row group label:


```r
htmlTable(mx, 
          css.rgroup = "",
          rgroup = c(paste("Group", LETTERS[1:2]), ""),
          n.rgroup = c(2,4,nrow(mx) - 6))
```

Column spanners
---------------

A column spanner spans 2 or more columns:


```r
htmlTable(mx,
          cgroup = c("Cgroup 1", "Cgroup 2"),
          n.cgroup = c(2,4))

It can sometimes be convenient to have column spanners in multiple levels:


```r
htmlTable(mx,
          cgroup = rbind(c("", "Column spanners", NA),
                         c("", "Cgroup 1", "Cgroup 2")),
          n.cgroup = rbind(c(1,2,NA),
                           c(2,2,2)))
```

Above example allows the column spanner to be a sum of the underlying cgroups (see n.cgroup), this is not required by the function:


```r
htmlTable(mx,
          cgroup = rbind(c("", "Column spanners", NA),
                         c("", "Cgroup 1", "Cgroup 2")),
          n.cgroup = rbind(c(1,5,NA),
                           c(2,1,3)))

Table spanners
--------------

A table spanner is similar to rgroup but has the primary purpose of combining 2 or more tables with the same columns into one:


```r
htmlTable(mx, 
          tspanner = paste("Spanner", LETTERS[1:3]),
          n.tspanner = c(2,4,nrow(mx) - 6))
```

Table caption
-------------

The table caption is simply the table description and can be either located above or below the table:


```r
htmlTable(mx[1:2,1:2], 
          caption="A table caption above")
```

<table class='gmisc_table' style='border-collapse: collapse;'  id='table_4'>
	<thead>
	<tr><td colspan='3' style='text-align: left;'>
	Table 5:  A table caption above</td></tr>
	<tr>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey;'> </th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>1st hdr</th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>2nd hdr</th>
	</tr>
	</thead><tbody>
	<tr>
		<td style='text-align: left;'>1st row</td>
		<td style='text-align: center;'>1:1</td>
		<td style='text-align: center;'>1:2</td>
	</tr>
	<tr>
		<td style='border-bottom: 2px solid grey; text-align: left;'>2nd row</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:1</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:2</td>
	</tr>
	</tbody>
</table>


```r
htmlTable(mx[1:2,1:2], 
          pos.caption = "bottom",
          caption="A table caption below")
```

<table class='gmisc_table' style='border-collapse: collapse;'  id='table_5'>
	<thead>
	<tr>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey;'> </th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>1st hdr</th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>2nd hdr</th>
	</tr>
	</thead><tbody>
	<tr>
		<td style='text-align: left;'>1st row</td>
		<td style='text-align: center;'>1:1</td>
		<td style='text-align: center;'>1:2</td>
	</tr>
	<tr>
		<td style='border-bottom: 2px solid grey; text-align: left;'>2nd row</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:1</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:2</td>
	</tr>
	</tbody>
	<tr><td colspan='3' style='text-align: left;'>
	Table 6:  A table caption below</td></tr>
</table>

A more interesting detail that the function allows for is table numbering, initialized by:


```r
options(table_counter = TRUE)
```


```r
htmlTable(mx[1:2,1:2], 
          caption="A table caption with a numbering")
```

<table class='gmisc_table' style='border-collapse: collapse;' >
	<thead>
	<tr><td colspan='3' style='text-align: left;'>
	Table 1:  A table caption with a numbering</td></tr>
	<tr>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey;'> </th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>1st hdr</th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>2nd hdr</th>
	</tr>
	</thead><tbody>
	<tr>
		<td style='text-align: left;'>1st row</td>
		<td style='text-align: center;'>1:1</td>
		<td style='text-align: center;'>1:2</td>
	</tr>
	<tr>
		<td style='border-bottom: 2px solid grey; text-align: left;'>2nd row</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:1</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:2</td>
	</tr>
	</tbody>
</table>

As we often want to reference the table number in the text there are two associated functions:


```r
tblNoLast()
```

```
## [1] 1
```

```r
tblNoNext()
```

```
## [1] 2
```

Table footer
------------

The footer usually contains specifics regarding variables and is always located at the foot of the table:


```r
htmlTable(mx[1:2,1:2], 
          tfoot="A table footer")
```

<table class='gmisc_table' style='border-collapse: collapse;'  id='table_1'>
	<thead>
	<tr>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey;'> </th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>1st hdr</th>
		<th style='border-bottom: 1px solid grey; border-top: 2px solid grey; text-align: center;'>2nd hdr</th>
	</tr>
	</thead><tbody>
	<tr>
		<td style='text-align: left;'>1st row</td>
		<td style='text-align: center;'>1:1</td>
		<td style='text-align: center;'>1:2</td>
	</tr>
	<tr>
		<td style='border-bottom: 2px solid grey; text-align: left;'>2nd row</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:1</td>
		<td style='border-bottom: 2px solid grey; text-align: center;'>2:2</td>
	</tr>
	</tbody>
	<tfoot><tr><td colspan='3'>
	A table footer</td></tr></tfoot>
</table>


Putting it all together
-----------------------

Now if we want to do everything in one table it may look like this:


```r
htmlTable(mx, 
          align="r",
          rgroup = paste("Group", LETTERS[1:3]),
          n.rgroup = c(2,4,nrow(mx) - 6),
          cgroup = rbind(c("", "Column spanners", NA),
                         c("", "Cgroup 1", "Cgroup 2&dagger;")),
          n.cgroup = rbind(c(1,2,NA),
                           c(2,2,2)),
          caption="A table with column spanners, row groups, and zebra striping",
          tfoot="&dagger; A table footer commment",
          cspan.rgroup = 2,
          col.columns = c(rep("none", 2),
                          rep("#F5FBFF", 4)),
          col.rgroup = c("none", "#F7F7F7"),
          css.cell = "padding-left: .5em; padding-right: .2em;")
```
