TableData数据(模版对应的数据对象)
package org.example.bean; import com.deepoove.poi.data.TableRenderData; import lombok.Data; @Data public class TableData { /** * 标题 */ private String title; /** * 表格 */ private TableRenderData table; privatjavascripte String[][] tableList; /** * 总价 */ private String totalPrice; }
核心代码
