Orient a JXTreeTable from bottom to top

Question

is there any way to orient a JXTreeTable from bottom to top? By this I mean that instead of the default layout like so:

Node 0
  |-     Node 0/Column 0      Node 0/Column 1
Node 1
  |-     Node 1/Column 0      Node 1/Column 1

I want the expanded rows to appear above the corresponding nodes, like so:

  |-     Node 0/Column 0      Node 0/Column 1
Node 0
  |-     Node 1/Column 0      Node 1/Column 1
Node 1
