JAVA输出表格（适配中英文）

1、TextForm

public class TextForm {

     * 左边距
     */

    /**
     * 右边距
     */

     * 标题
     */

     * 数据
     */

    /**
     * 最大列数
     */

    /**
     * 每个单元格最大字符数
     */
    protected int colMaxLength = 8;

    /**
     * 表格组成符号
     */

                }
            }
        }
        return textForm;
    }
}

　3、测试

public class TextFormTest {
	public static void main(String[] args) {
		TextFormBulider bulider = TextForm.bulider();
		bulider.setTitle("name", "age", "sex");
		bulider.addRow("王麻345子", "21", "男2");
		bulider.addRow("wzeefgrerhei", "21", "男");
		bulider.setColMaxLength(5);
		bulider.setSeparator('*');
		bulider.setPaddingL(2);
		bulider.setPaddingR(2);
		TextForm testForm = bulider.finish();
		testForm.printFormat();
		
	}
}
