I can't get the sort function to work properly.

Walvoord, John F. Daniel, The Key to Prophetic Revelation Moody, 1072
Walvoord, John F. Matthew Thy Kingdom Come Mooddy, 1974
Walvoord, John F. The Holy Spirit (3rd Edition) Zondervan,
Walvoord, John F. Armageddon, Oil and the Middle east Crisis Zondervan

In my document this data is in a three col table. If I manually sort it to put the last entry first and at a later time resort the document to alphabatize new entries, it moves the data back so that the Armageddon entry is last. If I put the data in a word document it sorts properly. I am trying to get away from Word, so I would like to see this work properly. Sorry, I could not figure out how to copy the table.
