How to merge two or three different tables in one?

I have big problem, I dont know how to merge two or more tables (with it data) into one new.
I need to transform my old mysql from my old site into new mysql structure for new site. What I want to do is to transform and copy only user details table from old to new. In old mysql user details are stored into 3 tables with some columns and in new table I have only one table with some columns. That 3 tables have same number of data rows and I array it by ID number. Because I dont need all columns from my user tables from old mysql, I will delete unnecessary columns and leave columns which I need for new table.
Now question, how I to merge this three tables to I get only one with certain table structure?
Too, I need when merge to copy and all user data which are now stored into that 3 tables and that user data to be merged.
Database is MyISAM, table 1, 2 and 3 had some same columns (ID of user and user status) but I delete it from table 2 and 3 because I need only one of it in new table.
Can anyone help me please?
Thank you very much, Mladen
