tells the resource timeline to render elements and call templates for non-allocated cells
Available only in PRO Edition
gantt.config.resource_render_empty_cells = true;
This functionality is available in the PRO edition only.
By default, the resource timeline won't call the resource_cell_value and resource_cell_class templates for cells that don't have any tasks allocated.
If this option is enabled, templates will be called for all cells of the resource timeline.
