We are looking for a proven JavaFX expert to develop a Pivot Table Control for us. As a reference you can look at Tableau and other data platforms for examples. We need a very clean minimal design. The main consideration is nested column and row headers. Filtering and sorting will be done by our OLAP engine. The columns does not have to be draggable but they should be resizable. Rows and columns can have n levels of nesting. See screenshot for more clarity. Row Labels, Column Labels, Column Titles all should be optionally hideable and styleable. An api like TableView would be nice. For values we may want to define a cell factory to configure colors and formats. We have lots of ongoing javafx needs and are looking to build a relationship with an expert starting with this project.
