Hi

sorry for my english

first, create new class

<code>

class ColorRowTable
    extends JTable {

  private int[] colorRows=new int[0];//table with numbers of our
colorful rows
  public Color rowColor=Color.red; //you can set your color
/*this method is always invoked when ui is updated*/
  public Component prepareRenderer(TableCellRenderer renderer, int
rowIndex, int vColIndex) {
    Component c = super.prepareRenderer(renderer, rowIndex, vColIndex);
    if (checkRow(rowIndex) && !isCellSelected(rowIndex, vColIndex)) {
      c.setBackground(rowColor);
    }
    else {
      c.setBackground(getBackground());
    }
    return c;
  }
/*compare index of actual row with rows to be painted*/
  private boolean checkRow(int index){
    boolean result=false;
    for(int i=0; i<this.colorRows.length && !result; i++){
      if(this.colorRows[i]==index){
        result = true;
      }
    }
    return result;
  }
/*sets rows to be painted*/
  public void setColorRows(int[] rowNumbers){
    colorRows=new int[rowNumbers.length];
    for(int i=0; i<rowNumbers.length; i++){
      colorRows[i]=rowNumbers[i];
    }
  }
  /*you can add, remove etc numbers of colorful rows*/
}

</code>
for example, in main code

<code>
ColorRowTable mytable=new ColorRowTable(); //
/*...do sth with this table...*/
/*if you have numbers of new rows*/
int[] index={/*for example*/1, 2, 5};
mytable.setColorRows(index);
mytable.rowColor=Color.....
mytable.updateUI();

</code>

sorry, if I missed sth
