How to get tax table value for invoice report?

[Valdis Vītoliņš]

I need to get name of Tax table name (because I have tax value in name)
http://code.gnucash.org/docs/HEAD/structGncTaxTable.html
Or better should be concatenated tax table name, entry amount and type
(e.g. VAT 21%, or VAT 10%)
http://code.gnucash.org/docs/HEAD/structGncTaxTableEntry.html

Usually we don't need to sum different tax table entries in one general
tax, so dealing with
several entries is hypothetical case and is important only for
localizations.

(Or, if I could choose which entry to use from several, I could define
one tax table "VAT" with entries 0%, 10%, 21%)
