tablecellrenderer

I'm trying to create a table and color specific cells either yellow, red or white, depending on the content of other columns. For that I am looping through the rows filling in the values and then checking on the contents. that works just fine for every row that is currently displayed on the screen, however when the program reaches rows that are not displayed or if the user try's to scroll every cell changes its backgroundcolor back to white. I have searched the web for solutions and the only idea that sounded reasonable was to reset the cellRenderer after each loop, which does not work because

I'm following some code I found, (Yes I understand how it works) It's from here : Code Link What i'm trying to do is set a cells Foreground color if the cells value is set to "yellow" Here is my Code: public class Board extends JPanel{ private static final long serialVersionUID = 1L; int boardHeight = 20; int boardWidth = 10; JTable table; public Board() { table = new JTable(this.boardHeight, this.boardWidth); table.setDefaultRenderer(String.class, new BoardTableCellRenderer()); table.setFocusable(false); table.setShowGrid(false); table.setRowMargin(0); table.setIntercellSpacing(new Dimension

I've set the TableCellRenderer for all the 3 columns like this (maybe not very effective?). for (int i = 0; i < 3; i++) { myJTable.getColumnModel().getColumn(i).setCellRenderer(renderer); } The getTableCellRendererComponent() returns a Component with a random background color for each row. How could I change the background to an other random color while the program is running? One way would be store the current colour for each row within the model. Here's a simple model that is fixed at 3 columns and 3 rows: static class MyTableModel extends DefaultTableModel {

I have created a JTable with a custom table render and custom cell editor which gives the result in the image I created the panel shown in the first table cells using a separate class which extended JPanel. and add table values as, tbl.setCellEditor(new customCell()); tbl.getColumnModel().getColumn(0).setCellRenderer(new customCell()); DefaultTableModel dtm = (DefaultTableModel) tbl.getModel(); Vector v = new Vector(); v.add(new Panel()); v.add("Test"); dtm.addRow(v); v.clear(); v.add(new Panel()); v.add("Test 2"); dtm.addRow(v); And this is my table custom class to create this table, class
