Formerly, for table sorting to function correctly, numbers had to be entered with not more than one thousands separator. As a workaround alphabetic sorting mode was applied, and the numbers provided with a hidden part so that alphabetic sorting corresponded with numeric sorting.
Since a mix in one column of numbers formatted for alphabetic sorting and plain numbers does not allow proper sorting, adding a number in an existing table may require putting it in the format used in that column. Also, if some table cells in a column contain text after the number, or if the numbers are preceded by some fixed text other than a currency symbol, alphabetic sorting mode is needed.
This template automatically creates the hidden <span style="display:none">&&&&&&&0123456789.&&1230</span> 123,456,789.00123 before the actual displayed number. It forces the sorting routine to use text sort on the hidden segment, which functions correctly due to the preceding ampersands (currently till 16 digits before, and 6 digits after the decimal separator).
Negative numbers do not sort correctly with this template.
