Hi,
try to override the method getColumnName in AbstractTableModel and return your column names. For Example
public String getColumnName(int col)
{
String[] colNames = {"A","B","C"};
return colNames[i];
}
and override the the method getColumnCount to return your column number
public int getColumnCount()
{
return 3;
}
i hope that works.
