JTable cell border color

Hi All,
How do i change the JTable's specific cell border color and set the cursor into that cell.
Thanks.

Write your own renderer.

JTable cell Background Color problem

I overriden the table renderer and tried to chenge the color of only that row which has greater value in the third column. I coded the logic but it set the color of all the rows. The custom tablecellrendere code is as follows
      public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,boolean hasFocus, int row, int column)
            cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
               if(vuti[0]==0)
                    //cell.setBackground(Color.pink);
                    vuti[0]=counter;
               else
                    if (counter>vuti[0] && !isSelected)
                      vuti[0]=counter;
                      cell.setBackground(Color.lightGray);
                  else if(counter<vuti[0])
                    cell.setBackground(Color.white);
            return cell;
      }

In the code that sets the background, you have a if - else (if - else if) structure. What's the default setting, when none of the 3 conditions are met?
And learn to indent your code correctly so that code blocks are readily apparent.

JTable cell background color

Hi All,
I want to change the background color of the same of the cells in jTabel. How can I do that.
Like, I want to keep 3 cells in red color. Another 2 cells in in green color, And keep other cell background color to default.
Also I want to change the background color of the cell, with different selection in other component(like jTree, jList).
Thank you,
Avin Patel

The same cell renderer is used by all cells of the table. You can't just set the background color of a cell once. You have to reset it every time the cell renderer is called (depending on which row/column you are being asked to render). Here is an example:
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
public class TableCell extends JFrame
     JTable table;
     public TableCell()
          Object[][] data = { {"1", "A"}, {"2", "B"}, {"3", "C"}, {"4", "D"} };
          String[] columnNames = {"Number","Letter"};
          DefaultTableModel model = new DefaultTableModel(data, columnNames);
          table = new JTable( model );
          // Set default cell renderer
          TableCellRenderer renderer = new TestRenderer();
          table.setDefaultRenderer(Object.class, renderer);
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
     public static void main(String[] args)
          TableCell frame = new TableCell();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible(true);
     class TestRenderer extends DefaultTableCellRenderer
          public Component getTableCellRendererComponent(
               JTable table,
               Object value,
               boolean isSelected,
               boolean hasFocus,
               int row,
               int column)
               super.getTableCellRendererComponent(table,
               value, isSelected, hasFocus, row, column);
               if (column == 0)
                    setHorizontalAlignment( LEFT );
                    setBackground( Color.blue );
               else
                    setHorizontalAlignment( RIGHT );
                    setBackground( Color.green );
               if (row == 1)
                    setBackground( Color.red );
               return this;
}

JTable cell border

Hi there,
I am trying without success to highlight a chosen cell in a JTable.
I have a JTable that sets up a setDefaultRenderer(). The cell renderer that I am using is a custom class that overrides DefaultTableCellRenderer.
I would have assumed that overriding the method thus:
public Component getTableCellRendererComponent(JTable table, Object value,
      boolean isSelected, boolean hasFocus, int row, int column) {
   this.setBorder (BorderFactory.createBevelBorder (EtchedBorder.RAISED));
   // Also tried...
   // setBorder( BorderFactory.createMatteBorder(0, 1, 0, 0, Color.black) );
   // setBorder(selectedBorder);
   // setBorder(BorderFactory.createLineBorder(Color.black));
   // setBorder(BorderFactory.createCompoundBorder(BorderFactory.createLineBorder(Color.black),getBorder()));
   // setBorder(BorderFactory.createLineBorder(Color.black));
   // setBorder(new EmptyBorder(1, 1, 1, 1));
   setBackground(new Color(0xE0C2FC));
}...would put a border around every cell in the table. But no, it does not. The setBackground() colours every cell though and that puzzles me. Does the setBorder() method indicate the border of the cell editor, not of the cell? IIs there another method I have to turn on like the conflict that occurs
when (JTable)
setRowMargin(0);
setShowHorizontalLines(true);stops the horizontal lines are showing.
Thanks in advance,
David

Hi Camickr,
Thanks for your responce. You are correct, the code example did not contain a:
return this;A quick search shows that you have answered very similar questions so many times, that I did not want to burden you (I posted when I saw that you were online) with superfluous code, so I stripped down to the bare core that would demenstrate my question. My appologies, it did not occur to me that you would actually want to compile it.
I have since foung the problem. I orginally based my TableModel and CellRenderer for my program on the Christmas Tree application:
http://java.sun.com/products/jfc/tsc/articles/ChristmasTree/
I relied heavily on the example at:
http://java.sun.com/products/jfc/tsc/articles/ChristmasTree/source/CTTableCellRenderer.java
As it turns out, the code in this example:
    // This override is only appropriate if this will never contain any
    // children AND the Graphics is not clobbered during painting.
    public void paint(Graphics g) {
        ui.update(g, this);
    }should not have been included into my implementation. The example file was using setBorders() all over the place. It never occured to me that they were being ignored.
I am not sure if it is to do with my implementaion of the example code or if the example was faulty to begin with. I am not wasting any more time on it, I have just rem'ed out the affending block and it is all working fine.
I thank you for your time though. Once again you have helped me to solve a problem.
David.

JTable - cell selection color

Hello.
I have this problem. Consider a JTable. When I select a cell it appears with a light blue background and a blue border. How do I change that blue border to red, for example?
Many thanks,
Afonso

You can change it for all tables using the UIManager. "Table.focusCellHighlightBorder" property. See [UIManager Defaults|http://www.camick.com/java/blog.html?name=uimanager-defaults] for more information.
For individual tables you could probably override the prepareRenderer(...) method to manually set the Border.

Cell border colors

I created a table with photos and text. In Dreamweaver the
text is yellow and borders are gray and all looks ok.
When I open it in Firefox the text and borders are yellow.
In Opera the same situation.
In Safari all is OK
Does anyone have any ideas? I am on a Mac
the page is

thanks

Huh? Do you mean table "width"? And you change it to zero?
Here's the relevant table tag -
<table width="200" border="3" align="center"
cellpadding="2" cellspacing="0"
bordercolor="#666666" bgcolor="#000000">
Note that you have used the IE proprietary (and thus invalid)
HTML attribute
"bordercolor". The reason that you do not see the gray
borders in Firefox
is that Firefox ignores this invalid HTML. If you want
colored table
borders, you will need to use CSS to specify them, not HTML.
For example,
you could have this -
<table width="200" align="center" cellpadding="2"
cellspacing="0"
style="border:3px solid #666;background-color:#000;">
to achieve the effect I think you want.

JTable cell with colored string

Hi,
How can I make colored string in cell (string with different colors) ?

Supposing you haven't used your own customized cell renderers, the following code must work..
((DefaultTableCellRenderer)<<yourtable>>.getCellRenderer(<row>, <col>)).setForeground(Color.BLUE);
This will paint all the cells of same type as cell(<row>, <col>) in blue.
If you want only certain cells in your table to be painted in a perticular colour, you may have to write a customized renderer yourself, extending the javax.swing.table.DefaultTableCellRenderer class, and override its getTableCellRendererComponent(...) method as per your required functionality.

Change cell's color in jtable when user clicks on it

Hi everyone,
i've got a JTable, and would like to change the background of a cell when user selects it
so i added a mouselistener over my jtable, the mousereleased method looks like this:
          public void mouseReleased(MouseEvent e) {
               int row = table.rowAtPoint(e.getPoint());
               int column = table.columnAtPoint(e.getPoint());
                        // help needed
          }as you see, i found the code to get the index of the cell selected, but i don't find any method in JTable class to get the cell component itself, and to alter its background color
Please notice that the "setSelectionBackground()" in JTable isn't enough, since i would also like to change the color of cells which are not selected when the user select a cell
how could i do that?
Thanks in advance!
edit: i tried the following but it does not work either
          public void mouseReleased(MouseEvent e) {
               int row = table.rowAtPoint(e.getPoint());
               int column = table.columnAtPoint(e.getPoint());
               AbstractTableModel atm = (AbstractTableModel) table.getModel();
               Component cell = table.getDefaultRenderer(CaseMemoire.class).
               getTableCellRendererComponent(table, atm.getValueAt(row, column), true, true, row, column);
               cell.setBackground(Color.MAGENTA);
               table.updateUI();
          }

ok i found how to do it
i directly inserted this in the renderer code:
if (row == table.getSelectedRow() && column == table.getSelectedColumn())
cell.setBackground(etc);
(curiously it does not work with "if (isSelected)")
thanks :)

I failed to color JTable cells

Hello,
I'm trying to set the background color of JTable cells based on their content.
For example if I edit a cell and put a R, I'd like to paint the background in Red.
If I enter B, I want it becomes Blue, and so on.
I tried to use a few examples found in various fora, but all failed.
in addition, I do not understand why I should extend JLabel and not another Class ?
Thanks for help.
Here is a sample code (in which all cells should become red whatever is typed in).
import javax.swing.table.*;
import javax.swing.*;
public class TableRenderer extends JLabel implements javax.swing.table.TableCellRenderer {
public java.awt.Component getTableCellRendererComponent
    javax.swing.JTable table,
   Object value,
   boolean isSelected,
   boolean hasFocus,
   int row,
   int column
     setBackground(java.awt.Color.red);   // for the moment All cells will be red
     return this;
   mytable = new javax.swing.JTable(5,5);
   TableColumn[] column = new TableColumn[5];
   TableColumnModel colModel = mytable.getColumnModel();
   for (int i=0; i <5 ;i++)
                column[i] = colModel.getColumn( i );
                column.setCellRenderer(new TableRenderer());

Finally after many tries I found a good way to do what I wanted.
If some people are interested, here is the code.
import java.awt.*;
import javax.swing.table.*;
import javax.swing.*;
class MyClass
public class TableRenderer extends javax.swing.table.DefaultTableCellRenderer
public Component getTableCellRendererComponent(JTable table,Object value,boolean isSelected,boolean hasFocus,int row,int column)
     Component xx = super.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);
        String val = (String) table.getValueAt(row, column);
        if (gegeutil.Gegetools.isEmpty(val)) super.setBackground(Color.white);
        else if(val.equals("Tournament")) super.setBackground(Color.red);
          else if(val.equals("Class"))super.setBackground(Color.orange);
          else if(val == "")           super.setBackground(Color.white);
        else super.setBackground(Color.blue);
               return xx;
public TableRenderer() {
     super();
JTable table = new JTable(nbrow, nbcolumn);
table.setDefaultRenderer(Object.class, new TableRenderer());
}

Dynamic colored in theh JTable cell

Hi, All
I am using a JTable to display a Jlable in the JTable cells.
The lable is divided to, say 10 , sub rectangles. I would liketo fill each rectangles with different bg colors depending on the data I received. I tried to use html in the JLable to control the color, however, it is very expensive cuase it involves a lot of string process and also it is difficult to control the dimension of those rectangles. Do anyone has any better idea to do this ?
The cell is not necessary to be a JLable, by the way.
Thanks in advance !

I have never used JPanel as my table cell component, but u might want to implement performance improvements similiar to ones done in DefaultTableCellRenderer which extends JLabel.
Here is the code extract from DefaultTableCellRenderer
* The following methods are overridden as a performance measure to
* to prune code-paths are often called in the case of renders
* but which we know are unnecessary. Great care should be taken
* when writing your own renderer to weigh the benefits and
* drawbacks of overriding methods like these.
* Overridden for performance reasons.
* See the Implementation Note
* for more information.
public void validate() {}
* Overridden for performance reasons.
* See the Implementation Note
* for more information.
public void revalidate() {}
* Overridden for performance reasons.
* See the Implementation Note
* for more information.
public void repaint(long tm, int x, int y, int width, int height) {}
* Overridden for performance reasons.
* See the Implementation Note
* for more information.
public void repaint(Rectangle r) { }

How to change a selected cell background color in JTable?

Hi all,
I am trying to change the background color of a selected cell by clicking on that particular cell. DefaultTableCellRenderer class provides setBackground(Color c) to change the background color of unselected cells. Is there a way to change a selected cell background color?
Thank you,
Arthur

Write your own renderer (eg. extending DefaultTableRenderer) and put in getTableCellRendererComponent method something like this:
if( isSelected && hasFocus )
setBackground( Color.RED );
setForeground( Color.GREEN );
}

Problem when setting JTable cell color.

hello,
when I setting color for particular table cell, it sets.
but, when I click another row (another cell) , the color of the previous cell disabled and it visible only when I click that cells row.
how can I permanatly set the color for the rows depends on input data.
for example,
if a device is connected, I want to give the cell color GREEN.
if device is not connected , i want to give the color as RED.
thank you.

but, when I click another row (another cell) , the color of the previous cell disabled and it visible only when I click that cells row.It appears you applied color to cell editor.
tableObj.getComponentAt(x,y).setForeground(Color.red);
tableObj.getComponentAt(x,y).setBackground(Color.red); or could be solved properl if you post the code

I think Problem is between these code only
for(int k=0;k<columnCount;k++)
               TableCellRenderer renderer = null;
               TableCellEditor editor = null;

class TextAreaCellRenderer extends JTextArea implements TableCellRenderer
     public TextAreaCellRenderer() {
          setEditable(false);
          setLineWrap(true);
          setWrapStyleWord(true);
     public Component getTableCellRendererComponent(JTable table,
          Object value, boolean isSelected, boolean hasFocus,

          if (value instanceof String)
               setText((String)value);
          // Adjust row's height
          int width = table.getColumnModel().getColumn(nCol).getWidth();
          setSize(width, 1000);
          int rowHeight = getPreferredSize().height;
          if (table.getRowHeight(nRow) != rowHeight)

Selected Table Cell Border in 1.4.2

Hi All!!
I am facing a problem with JDK 1.4.2_01 & Windows L&F. I am unable to see the yellow border around the selected cell in JTable. Was working fine with 1.4.1_03.
A bug with id: 4674205 was reported with 1.4.0 stating :
" In the Windows Look and Feel, the selected cell in a JTree or JTable is framed with a yellow rectangle. To accurately match the real Windows UI, it should be a black and white dotted rectangle instead. (This was part of bug 4268204,which was marked fixed, but this part hasn't been fixed.) This behavior was fixed for JList, but not JTree or JTable. "
Now it has been fixed and closed.
May be they might have removed setting of yellow border for the selected cell to match with native windows UI.
But selected cell border is very much necessary for my project. Can any one please suggest me a workaround.
With Regards,
LRK

Hi Sai!
Thanks for your reply. It will not be feasible in my application as it already has huge number of tables with some of them already having complex renderers and editors.
I was looking at something which i can set globally so that it will reflect to all of the tables in the application in a particular L&F.
I tried setting
UIManager.getDefaults().put("Table.focusCellHighlightBorder",Color.yellow);
and
UIManager.put("Table.focusCellHighlightBorder",Color.yellow);
But no luck.
Any other inputs are most welcome.
With Regards,
LRK
