the class FillTempTest method complexFill.

/**
 * 复杂的填充

 * @since 2.1.1
 */
@Test
public void complexFill() {
    // 模板注意 用{} 来表示你要用的变量 如果本来就有"{","}" 特殊字符 用"\{","\}"代替
    // {} 代表普通变量 {.} 代表是list的变量

    ExcelWriter excelWriter = EasyExcel.write(fileName).withTemplate(templateFileName).build();
    WriteSheet writeSheet = EasyExcel.writerSheet().build();
    // 这里注意 入参用了forceNewRow 代表在写入list的时候不管list下面有没有空行 都会创建一行，然后下面的数据往后移动。默认 是false，会直接使用下一行，如果没有则创建。
    // forceNewRow 如果设置了true,有个缺点 就是他会把所有的数据都放到内存了，所以慎用
    // 简单的说 如果你的模板有list,且list不是最后一行，下面还有数据需要填充 就必须设置 forceNewRow=true 但是这个就会把所有数据放到内存 会很耗内存
    // 如果数据量大 list不是最后一行 参照下一个
