Question

我需要将txt文件转换为一个Excel文件，并进一步格式化每个工作簿。将所有txt文件转换为excel已完成，但问题是根据其行和列格式化每个工作表。例如，在第一张表中需要合并（0,0,14,18），在第二张表中需要合并（1， 2,0,0）。我尝试使用sheet.addMergedRegion（new CellRangeAddress（0,0,14,17））;但它将合并所有工作表的相同单元格。下面是我的代码plz帮助。

Answer 1

sheet.addMergedRegion(new CellRangeAddress(0,0,14,17));循环中有for。这将合并您正在创建的所有工作表的这些范围。

您需要添加一个验证（例如计算迭代的简单变量i），并合并每次迭代所需的范围。

在你的情况下，它可能是

if(i==0){
    //first sheet
    sheet.addMergedRegion(new CellRangeAddress(0,0,14,17));
} else if (i==1){
    //second sheet
    sheet.addMergedRegion(new CellRangeAddress(1,2,0,0));
}
