This function should generate a string that uniquely identifies a piece
of data present in a table. In a report with multiple tables the id
is used to preserve uniqueness.

Provides an extensible formula system to quickly and easily create
production quality tables. The processing steps are a formula parser,
statistical content generation from data as defined by formula, followed by
rendering into a table. Each step of the processing is separate and user
definable thus creating a set of composable building blocks for
highly customizable table generation. A user is not limited by any of the
choices of the package creator other than the formula grammar. For example,
one could chose to add a different S3 rendering function and output a format
not provided in the default package, or possibly one would rather have Gini
coefficients for their statistical content in a resulting table. Routines to
achieve New England Journal of Medicine style, Lancet style and
Hmisc::summaryM() statistics are provided. The package contains rendering
for HTML5, Rmarkdown and an indexing format for use in tracing and tracking
are provided.
