使用picocli格式化java表格输出

Question

我希望格式化此代码：

Object[][] table = new String[4][];
table[0] = new String[] { "Pie", "2.2", "12" };
table[1] = new String[] { "Cracker", "4", "15" };
table[2] = new String[] { "Pop tarts", "1", "4" };
table[3] = new String[] { "Sun Chips", "5", "2" };
String itemId = CommandLine.Help.Ansi.AUTO.string("@|bold,green,underline ItemId|@");
System.out.format("%-15s%-15s%-15s%-15sn", itemId, "Item", "Price", "Quantity");
for (int i = 0; i < table.length; i++) {
Object[] row = table[i];
System.out.format("%-15d%-15s%-15s%-15sn", i, row[0], row[1], row[2]);
}

这是早期堆栈交换问题(java格式化表格输出(的衍生示例

然而，使用我的标记字符串，而不是获得正确的选项卡式标题，我得到了这个。

怎么回事？

奇怪，我觉得不错。

代码：

import picocli.CommandLine; 
public static void main(String... args) {
Object[][] table = new String[4][];
table[0] = new String[]{"Pie", "2.2", "12"};
table[1] = new String[]{"Cracker", "4", "15"};
table[2] = new String[]{"Pop tarts", "1", "4"};
table[3] = new String[]{"Sun Chips", "5", "2"};
String itemId = CommandLine.Help.Ansi.AUTO.string("@|bold,green,underline ItemId|@");
System.out.format("%-15s%-15s%-15s%-15sn", itemId, "Item", "Price", "Quantity");
for (int i = 0; i < table.length; i++) {
Object[] row = table[i];
System.out.format("%-15d%-15s%-15s%-15sn", i, row[0], row[1], row[2]);
}
} ```
output: 
ItemId         Item           Price          Quantity       
0              Pie            2.2            12             
1              Cracker        4              15             
2              Pop tarts      1              4              
3              Sun Chips      5              2
