index of tables doesn't update

users
#1

I am writing a document for a client (translating it from Spanish to
English), and it requires an Index of Tables.

I successfully planted such an index after the table of contents, but when
I do

All Indexes and Tables

the Table of Contents updates with all relevant headings, but nothing
happens in the Index of Tables.
It's not listing the tables.

This is with LO4, both on Debian Wheezy and on Windows 7.

Any an all assistance appreciated, in advance.

Thanks,
Tony
