as.data.table.Composite_table

as.data.frame.Composite_table

As a <code>Composite_table</code> already is a <code>data.table</code> this function
does very little except stripping all additional attributes and classes,
as well as offering you the option to prepend the <code>multinames</code> before
the column names

Functions to combine data.frames in ways that require additional effort in
base R, and to add metadata (id, title, ...) that can be used for printing and
xlsx export. The 'Tatoo_report' class is provided as a
convenient helper to write several such tables to a workbook, one table per
worksheet. Tatoo is built on top of 'openxlsx', but intimate knowledge of
that package is not required to use tatoo.
