jQuery Grid Plugin - jqGrid

Allow dragging and dropping of leaf's and branches (with children).  Currently, once gridTree is true, dragging and dropping and even sortableRows becomes disabled.

A good example is jsTree.com with its drag and dropping

Maybe if a column was a tree, it would be better to actually set rowcount=rows so that one cell holds the tree, and space each node's height the same as each table cell (note different browsers measure the border differently, some such as Chrome include the border thickness in the cell height and IE just ignores web standards).
