My solution is custom table cell render. I not sure the flatlaf have the properties style

table.setShowVerticalLines(true);
applyStye(table, 0);

private void applyStye(JTable table, int colIndex) {
    final TableCellRenderer oldCellRender = table.getDefaultRenderer(Boolean.class);
    table.getColumnModel().getColumn(colIndex).setCellRenderer(new DefaultTableCellRenderer() {
        @Override
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            Component com = oldCellRender.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
            if (isSelected) {
                com.setBackground(UIManager.getColor("Table.selectionBackground"));
            } else {
                if (row % 2 != 0) {
                    com.setBackground(UIManager.getColor("Table.alternateRowColor"));
                } else {
                    com.setBackground(UIManager.getColor("Table.background"));
                }
            }
            return com;
        }
    });
}

Here My FlatLaf.properties

Table.alternateRowColor=#F5F5F5

Table.gridColor=#D6D6D6
Table.intercellSpacing=1,1

The problem is that the boolean renderer (see class JTable.BooleanRenderer) does not support alternating row colors. This is IMHO actually a bug in Swing...

Because that boolean renderer is implemented and set in JTable, I actually thought that it would be a bad idea to replace it in FlatLaf. But now I found out that other L&Fs (Nimbus, Radiance, ...) do replace that boolean renderer. So I'm going to do the same in FlatLaf... 😄
