There are space margin between filter and tree table component

I dont know why everytime i add tree table component with filter component, there are spaces margin between the two components.
Is it bug ?

Could you provide your screen layout (the part with the filter and table is enough) and a screenshot with an indication of what you think is the undesirable spacing?

Please check the attached files. if i change the component into generic table, it is displayed correctly



Did you expand the table? Please try to set “departmentTable” in the “expand” property of the “layout” element.

Thanks Krivopustov!
