Aww yeah, appendGrid for Bootstrap 4 is coming!
Custom Buttons
Extra buttons can be added at the end of each row by using `customRowButtons` parameter. By default buttons are appended at the end that cell but you can change the `atTheFront` option to make it at the front. You can apply all the jQuery UI Button widget options to the new generated buttons such as primary and secondary images.

After v1.3.1, extra buttons can be added at the bottom row of grid by using `customFooterButtons` parameter. The buttons configuration are the same as `customRowButtons`.

After v1.3.5, the standard grid buttons are fully customable. You can change the icon, add text to the button or even use another button to replace the default one. Please try this demo or check the `customGridButtons` initial parameter.
