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();
}
};
});
