JTable TableCellRenderer 没有正确着色

JTable TableCellRenderer not coloring correctly

我用我的自定义 DefaultTableCellRenderer 创建了一个简单的 JTable。它本身运行良好(为最后一列着色)。但是一旦我 select 一行或 filter/unfilter 它,该行就会被着色,即使它根本不应该被着色。

我的渲染器:

public class StatusCellRenderer extends DefaultTableCellRenderer {
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
            int row, int col) {
        Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus,
                table.convertRowIndexToModel(row), col);
        DataTableModel model = (DataTableModel) table.getModel();
        String data = model.getValueAt(table.convertRowIndexToModel(row), col).toString();
        if (col == 3 && data.equalsIgnoreCase("successful") && !data.isEmpty()) {
            c.setBackground(Color.GREEN);
        }
        if (col == 3 && !data.equalsIgnoreCase("successful") && !data.isEmpty()) {
            c.setBackground(new Color(255, 51, 51));
        }
        return c;
    }
}

它最初的样子(以及它应该看起来的样子):

并且在 selecting 2 行(顶部和底部)之后:

如您所见,有几行是绿色的,根本不应该着色。更令人不安的是,我只 select 编辑了绿色块的顶部和底部行,这意味着它也会自动为中间的行着色。

我怎样才能停止这种行为并只为第一张图片中显示的行着色?


接受的答案对我解决问题很有帮助,这是最终代码:

public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
        int row, int col) {
    Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus,
            table.convertRowIndexToModel(row), table.convertColumnIndexToModel(col));
    DataTableModel model = (DataTableModel) table.getModel();
    String data = model.getValueAt(table.convertRowIndexToModel(row), table.convertColumnIndexToModel(col))
            .toString();
    if (!isSelected) {
        if (col == 3 && data.equalsIgnoreCase("successful") && !data.isEmpty()) {
            c.setBackground(Color.GREEN);
        } else if (col == 3 && !data.equalsIgnoreCase("successful") && !data.isEmpty()) {
            c.setBackground(new Color(255, 51, 51));
        } else {
            c.setBackground(Color.WHITE);
        }
    } else {
        c.setBackground(c.getBackground());
    }
    return c;
}

如果单元格 selected,它会显示蓝色,如果没有,则根据值

显示白色、绿色或红色

由于渲染器组件将被重复使用,考虑在没有条件匹配时设置默认颜色:

    if (col == 3 && data.equalsIgnoreCase("successful") && !data.isEmpty()) {
        c.setBackground(Color.GREEN);
    }
    else if (col == 3 && !data.equalsIgnoreCase("successful") && !data.isEmpty()) {
        c.setBackground(new Color(255, 51, 51));
    }
    else {
        c.setBackground(Color.GRAY.brighter());
    }
