I don't understand this. Drag and drop happens in the table body. Column 
resizing and reordering happens in the table header. How does this 
interfere?

Adding a dragstart handler to the table should be sufficient.

Example:
myTable.addEventListener("dragstart", function(evt) {
   var pageX = evt.getPageX();
   var pageY = evt.getPageY();

   var tableScroller = myTable.getTablePaneScrollerAtPageX(pageX);
   if (tableScroller != null) {
     var row = tableScroller._getRowForPagePos(pageX, pageY);

     if (row != null && row != -1) {
       // We are over a row -> Start dragging
       evt.addData("mytype", getDataFromRow(row));
       evt.addAction("move");
       evt.startDrag();
     }
   };
});
