The ability to group rows in a table can let an end user quickly and easily see the structure of the data shown, and also present them with summaries of the data shown in each group. Row group adds this ability to customize the start and end grouping rows displayed in the Datatable, letting you integrate the summarised data to fit perfectly in with your site.

Row group can be initialised on a Datatable by using rowGroup option in the Datatable option object. In most circumstances you will wish to also set the rowGroup.dataSrc option to tell Datatable which data point in the data source to use for initial grouping.

It can often be useful to have grouping rows at the start and the end of a group to show different summary information about the group. Row group provides two rendering options - rowGroup.startRender and rowGroup.endRender - as the naming implies, one for the group start and one for the group end, allowing them be configured independently

Row group provides the ability to group data a multiple levels. This example show the rowGroup.dataSrc option being used as an array to specify the Office as the top level group and Position as second level.
