Tools->export tables contains three ways to export:

Three ways can be exported table structure and data, online said three methods are different, as follows:

Oracle export,sql insert,pl/sql Developer

The second is exported to. sql files, available text Editor view, versatility is better, but less efficient than the first, suitable for small data import and export, especially note that the table can not have a large number of fields (Blob,clob,long), if there is, you will not be prompted to export (prompted as follows:
table contains one or more LONG columns cannot export in SQL Format,user PL/Developer format instead) can be exported in the first and third ways.
