+Table Data
+##########
+
+These functions let you fetch table information.
+
+$this->db->list_tables();
+==========================
+
+Returns an array containing the names of all the tables in the database
+you are currently connected to. Example::
+
+	$tables = $this->db->list_tables();
+	
+	foreach ($tables as $table)
+	{
+		echo $table;
+	}
+
+$this->db->table_exists();
+===========================
+
+Sometimes it's helpful to know whether a particular table exists before
+running an operation on it. Returns a boolean TRUE/FALSE. Usage example::
+
+	if ($this->db->table_exists('table_name'))
+	{
+		// some code...
+	}
+
+.. note:: Replace *table_name* with the name of the table you are looking for.
