 This objects defines details for each row if the chosen _type_ of method for buttons and/or rows (defined in _operations/buttons_ and/or in _operations/row_) is *redirect_custom*. The examples very well explains what is needed.
   * *buttons*: is an *object* which has more than one object inside, indexed by a key. This key is the _id_ defined formerly in _operations/buttons/id_. In this case, the id of the button chosen is _"edit"_. redirect_custom method needs a *caption* (a *string*), which defines what the caption of the button should show when the user clicks on that very row, and a *link* (a *string*) which will be the page where the user should be redirected when that very row is selected and the button is clicked.
   * *row*: is an *object*, which contains only a *link* option, which is a *string* that contains an URL. That string defines where the user should be redirected when clicking on a row.
-  * *row_buttons* is an *object* which has more than one object inside, indexed by a key. This key is just for reference, to make it unique between all the row buttons. The *caption* (a *string*) defines the caption of the button once is appended to the *append_to_column* (another *string*) column of the row it refers to. *append_to_column* must be a valid column _name_ in the _colModel_ array (see _configurations/colModel_). *type* and *parameters* follow the same rules as per the global _buttons_ in _operations_ objects (see _operations/buttons_). Only *redirect_simple* is enabled at the moment. It is suggested not to have any row operation if you enable row buttons, as to do so will have no effect when clicking the buttons, since the row operation will take precedence.
