Fire update array header

Question

Hi!
I created my own array that uses my own DataArrayModel (extending AbstractTableModel). The data used in the DataArrayModel comes from a vector within the class.
At first, the vector is empty and there is no array (no header) displayed. When I add the first element in the vector, the array doesn't refresh. The header nor the row are diplayed. I tried to call updateUI and update(null) on the array, fireTableStructureChanged(), fireTableDataChanged() and fireTableRowsInserted(...) on the model and repaint() on the panel containing the array, but it doesn't work. If there is already data in the array and new one is added, a simple call to fireTableDataChanged() works.
How to update the array including its header?
Thank you,
MarieDM

Somehow, I changed code and the following now works:
tableModel.update();
tableModel.fireTableStructureChanged();
tableModel.fireTableDataChanged();
