Hey thanks for replying.
With code like that:
public class yellowCellRenderer
  extends DefaultTableCellRenderer
  private int whichRow = 0;
  public yellowCellRenderer(int saveToRow)
    this.whichRow = saveToRow;
  public Component getTableCellRendererComponent(JTable table, Object value,
    boolean isSelected, boolean hasFocus, int row, int column)
    if(this.whichRow == row){
     this.setBackground(Color.YELLOW);  // All columns verified were empty - set our background RED
    return this;
}and usage:
     comments.add(comment);
     JTable table = getMainTable();
     TableColumnModel colModel = table.getColumnModel();
     for(int i=0;i<comment.length;i++){
         if(!Main.isStringEmpty((String)comment)){
          TableColumn column = colModel.getColumn(i);
          column.setCellRenderer(
               new yellowCellRenderer(table.getRowCount()-1)
Every each cell in column gets yellow background... What am I doing wrong?
