PHP object-oriented development

Some problems with PHP object-oriented development the following code is a method in the class:
Public function getHead (){
$ Map = array (
'A. status' => array ('EQ ', 1 ),
'A. recommend' => array ('EQ ', 1)
);
$ Prefix = C ('Db _ prefix ');
$ Data = $ this-> Table ("{$ prefix} auction as A")->
Join ("{$ prefix} accessory as ac on a. goods_pic = AC. id")->
Join ("{$ prefix} accessory as acc on a. agopic = ACC. id")->
Field ('A. *, AC. path, ACC. path as agopath ')-> where ($ map)->
Find ();
Return $ data;
}

In the following code, $ this-> Table ("...") cannot be found anywhere! Why? Please advise!
$ Data = $ this-> Table ("{$ prefix} auction as A")->
Join ("{$ prefix} accessory as ac on a. goods_pic = AC. id")->
Join ("{$ prefix} accessory as acc on a. agopic = ACC. id")->
Field ('A. *, AC. path, ACC. path as agopath ')-> where ($ map)->
Find ();

Does the current class or its parent class have the Table method?

The class of your method is inherited from a database base class (or a base class)
If you do not find the table method definition in this class (or its parent class), you must define a _ call method.

Absolutely does not exist!

You can find it in the mysql class.

Experts are experts! Just a word! The _ call method is indeed a method that often works! Neglected! This is the case for me! Thank you very much!
