Display a tabular object using HTML.
This is similar to print.tabular
, but it inserts the code to
display the table in an HTML table.
toHTML(object, file = "", options = NULL, id = NULL, append = FALSE, browsable = TRUE, ...) html.tabular(object, ...) writeCSS(CSS = htmloptions()$CSS, id = NULL)
object |

file |

options |

id |
A unique identifier to set for this table and the associated
CSS style, or |
append |
If |
browsable |

The toHTML()
function produces HTML output suitable for inclusion in an HTML page.
The html.tabular
function is set up
to work as a method for the html
generic in Hmisc,
but is not registered as a method, so that tables can
work when Hmisc is not installed.
In HTML, it is mainly the CSS style sheet that determines the look of the table.
When formatting a table, html.tabular
sets the CSS class according to the
table's Justify
setting; justifications of c("l", "c", "r")
are
translated to classes c("left", "center", "right")
respectively; other strings
will be passed through and used directly as class names.
If the id
value is not NULL
, then it will be used
as the CSS id selector when searching for a style.
See table_options
for a number of options that control formatting, including
the default style sheet.
The toHTML()
function creates an HTML object using the
htmltools::HTML
function.
