如何更改JTable中第一个单元格的背景颜色？

Question

Is everything okay?

I have the following table in my java application. By the status he makes the line a certain color, as I will show in the code below.

What I want is that only the first column is colored, the others want to appear with the default color.

public class PriorityCellRenderer extends DefaultTableCellRenderer {
@Override
public Component getTableCellRendererComponent(JTable table, Object value,
        boolean isSelected, boolean hasFocus, int row, int column) {
    super.getTableCellRendererComponent(
            table, value, isSelected, hasFocus, row, column);

    //if (Integer.valueOf(1).equals(table.getValueAt(row, 1)) && 0 == column)   && 9 < column)
    if (String.valueOf(1).equals(table.getValueAt(row, 0))) {
        setForeground(Color.BLUE);  // or background
    }
    if (String.valueOf(2).equals(table.getValueAt(row, 0))) {
        setForeground(Color.GREEN);  // or background
    }
    if (String.valueOf(3).equals(table.getValueAt(row, 0))) {
        setForeground(Color.YELLOW);  // or background
    }
    if (String.valueOf(4).equals(table.getValueAt(row, 0))) {
        setForeground(Color.RED);  // or background
    }
    return this;
} 
}

Realized my question?

Does anyone can help me please?

Thank you very much.

1. Set custom renderer for target column:

    table.getColumnModel().getColumn(COLUMN_INDEX).setCellRenderer(new PriorityCellRenderer()); 

2. in getTableCellRendererComponent() validate column index if(column == COLUMN_INDEX)
