The LaTeX-package ``fcolumn''
In financial reports, text and currency amounts are regularly put in
one table, e.g., a year balance or a profit-and-loss overview.
This package provides the settings for automatically typesetting
such columns, including the sum line (preceded by a rule of the correct
width), using the specifier ``f''.
The column specifier f itself is rather simple. It is the predefined
version of a generic column F. The generic version expects three
arguments: |#1| is the separator, |#2| is the decimal mark, and |#3|
the coding used for grouping digits of the integer part and decimal
part. For example the f-column in the current version of the package
is using 3.2 as #3, meaning that numbers are typeset with 2 decimal
digits and grouping is done on 3 digits. The decimal separator is
``,'' and the grouping character is ``.'', thereby coding for the
continental European standard. People in the Anglo-saxon world would
rather code |\newcolumntype{f}{F{,}{.}{3,2}}|.
To show where and how the f-column is used, let's look at a typical
financial table.
properties 31 dec 2014 debts 31 dec 2014
-----------------------------------------------------
house 200.000,00 equity capital 50.000,00
bank account -603,23 mortgage 150.000,00
savings 28.000,00
cash 145,85 profit 27.542,62
---------- ----------
227.542,62 227.542,62
The core part of the table is input as
\begin{table}
\begin{tabular}{lflf}
house & 20000000 & equity capital & 5000000\\
bank account & -60323 & mortgage & 15000000\\
savings & 2800000\\
cash & 14585 & profit & 2754262\\
\sumline
\end{tabular}
\end{table}
The column specifier ``f'' (for ``finance'') is able to do the
typesetting. It constructs the sum line, typesets the numbers,
calculates the totals, and checks whether the two columns are in
balance; if not, the user is warned via a message. A special command
\resetsumline exists which alllows one to restart a table, so that
multiple tables in one tabular environment are possible.
