代码

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;

    private String[][] tableList;

    /**
     * 总价
     */
    private String totalPrice;

}
