我有一個4列的鞦韆桌。字符串，布爾（複選框），字符串，按鈕。我將一個按鈕傳遞給它，並且我得到了我知道會發生的按鈕字符串。所以我開始設置一個自定義表格渲染器來渲染按鈕，但是我收到了一個異常，我不確定它想告訴我什麼。Java Table Rendered
這是我的渲染類：
JtableButtonRendereer implements TableCellRenderer {
@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
JButton button = (JButton) value;
if (isSelected) {
button.setForeground(table.getSelectionForeground());
button.setBackground(table.getSelectionBackground());
} else {
button.setForeground(table.getForeground());
button.setBackground(UIManager.getColor("Button.background"));
}
return button;
}
}
這是我使用設定渲染
imageTable.getColumn("TwitterFeed").setCellRenderer(new JtableButtonRendereer());
什麼，這是我得到的錯誤：

錯誤來自我設置新渲染器的行。建議？
