java - 设置 jtable 某些行的前景色

Question

我创建了一些costum单元渲染来改变我的jtable的外观，我改变了一些行的颜色和字体，我尝试做同样的事情，但它不起作用，这是我的代码:

@Override
            public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
                Component c = super.prepareRenderer(renderer, row, column);
                int firstRow = 0;
                int lastRow = jTable1.getRowCount() - 1;
                if (row == lastRow) {
                    ((JComponent) c).setBackground(new Color(218, 244, 247));
                //((JComponent) c).setFont(new java.awt.Font("Tahoma", 1, 12));
                } else if (row == firstRow) {
                    ((JComponent) c).setBackground(new Color(218, 244, 247));
                    ((JComponent) c).setFont(new java.awt.Font("Tahoma", 1, 12));
                     ((JComponent) c).setForeground(new Color(11, 114, 126));
                } else if (row == 5) {
                    ((JComponent) c).setBackground(new Color(218, 244, 247));
                    ((JComponent) c).setFont(new java.awt.Font("Tahoma", 1, 12));
                } else {
                    ((JComponent) c).setBackground(jTable1.getBackground());
                }

                return c;
            }

这就是我遇到问题的时候:

((JComponent) c).setForeground(new Color(11, 114, 126));

if (row == firstRow) {
((JComponent) c).setBackground(new Color(218, 244, 247));
((JComponent) c).setFont(new java.awt.Font("Tahoma", 1, 12));
((JComponent) c).setForeground(new Color(11, 114, 126));}

谢谢

, i changed color of some rows, and font, i tried to do the same but it doesn't work, this is my code :

• 工作正是为 prepareRenderer ，您的问题必须存在于代码的其余部分中(正如我们可以看到您之前的线程)，为了更好地帮助，请尽快发布 SSCCE ，短，可运行，可编译，大约JFrame和JTable与 prepareRenderer

• for example the same/similair code

• 但需要覆盖 convertXxxToModel ，因为ColumnModel could be reordered and/or rows can be sorted or filtered ，在本例中索引为 JTables view与索引 XxxTableModel 不同，然后 XxxRenderer无法正常工作
