Java JTable Alternate Row Color not working
java, jtable, swing, tablecellrenderer
Solution
Recently while going through the source code of javax.swing.table.DefaultTableCellRenderer, I found following simple solution which will provide alternate row coloring for all tables in an application.
In the code, just after setting default look and feel insert following code:
UIDefaults defaults = UIManager.getLookAndFeelDefaults();
if (defaults.get("Table.alternateRowColor") == null)
defaults.put("Table.alternateRowColor", new Color(240, 240, 240));
Problem
Why this following code not working? where is the problem? My jTable is initiated as jTable1; ``` jTable1.setDefaultRenderer(Object.class,new TableCellRenderer(){ @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { Component c = (Component) table.getCellRenderer(row, column); c.setBackground(row%2==0 ? Color.white : Color.yellow); return c; }; }); ```
