Using version: mdbtools-0.7.1-3.el7.x86_64 under CentOS 7
The scripts: mdb-schema and mdb-export do not properly handle table names with spaces in them, specifically in the IF EXISTS DROP lines in mdb-schema, and in the INSERT lines created in mdb-export. It appears any data for a table with a space in the name will not be exported.
Additional info... using the MySql export option.
