What I did was the following (probably it can be more efficient but for 
now it will suffice):
- Every object in the table is represented in an objRowMap (could prob 
be something pagebound as well)
- When row/ obj is deleted you can remove it from the map, get the obj 
from the map and remove the obj from the db as well (if a db delivers 
you the data) also remove the row from the current TableDataModel
- The table is now ok
- There is always the infamous multi-user discussion re. the above 
behaviour so I won't go there.
- The table now redraws itself without the deleted object
- Done (or so it is in my code)

Following a code snippet concerning the deleteRow action:
The rows are determined through a checkbox or a link
  /**
   * Generates the context that will be passed to the deleteRow() 
listener  if a "remove" link is selected.
   * This is used by the Block rendering the 'Delete' column.
   * @return String[] the context for the deleteRow() listener
   */
  public String[] getDeleteRowContext() {
    Object objRow = getCurrentRow();
    return new String[] { objRow.toString() };
  }

  /**
   * A listener invoked when a "remove" link is selected.
   * It removes from the data model the row corresponding to the link.
   * @param objCycle the request cycle
   */
  public void deleteRow(IRequestCycle cycle) {
    Object[] arrParams = cycle.getServiceParameters();
    Object o = _objectLinkMap.get(arrParams[0]);
    // Remove or do what you have to do from a dataSource perspective
    if (o instanceof PersistentDCG) ((PersistentDCG) o).delete(((Visit) 
cycle.getEngine().getVisit(cycle)).getUser());
    // Remove the row from the current TableDataModel
    ((SimpleListTableDataModel) ((SimpleTableModel) 
getTableModel()).getDataModel()).removeRow(o);
    // Remove the row from the temporary map
    _objectLinkMap.remove(arrParams[0]);
  }

Good luck,
