Can MySQL database synchronization be synchronized for a single table? What to do with it

Can MySQL database synchronization be synchronized for a single table?
First question:
Can MySQL database synchronization be synchronized for a single table?

Other words
1. There are a1,a2,a3 three tables in database A, and there is only one A1 table in database B (the same as the table structure of the A1 of A and B)
2. Database B synchronizes only the A1 tables in database A
3. Database A also synchronizes B's A1 table

Note: In fact, can be considered as database A and database B A1 table bidirectional synchronization, that is, a database A1 data changes, b database A1 also to change, the same way b database A1 changes, a database A1 also change (AA1<=>BA1)

Second question:
Configure database synchronization does Linux have the same configuration as Windows?
------to solve the idea----------------------
Synchronization is for a single table, such as the need for more than one table to be listed. Of course, you can also set the entire database synchronization
