Custom your table display records length. In this version i have added to custom you record display drop down values, just simple pass a comma separated integer text value into lengthMenu input parameter.

Note: if you pass a single value (ex: lengthMenu: "25" ) the length option will not get displayed

Example:

lengthMenu: "20" ----Vaild

lengthMenu: "10, 25, 50, 100" ----Valid

lengthMenu: "10; 25; 50; 100" ----Not Valid
