//匯出


// 第一步，建立乙個webbook，對應乙個excel檔案 


hssfworkbook wb = new hssfworkbook(); 


// 第二步，在webbook中新增乙個sheet,對應excel檔案中的sheet 


hssfsheet sheet = wb.createsheet("sheet1"); 


// 第三步，在sheet中新增表頭第0行,注意老版本poi對excel的行數列數有限制short

//設定樣式


row.setheight((short) 400);


hssfcellstyle style = wb.createcellstyle();


style.setverticalalignment(hssfcellstyle.vertical_center);//垂直居中 


style.setalignment(hssfcellstyle.align_center);//水平居中 


//設定字型 


hssffont font = wb.createfont(); 


font.setfontheightinpoints((short) 10);//設定字型大小 


font.setboldweight(hssffont.boldweight_bold);//粗體粗細 


style.setfont(font);//選擇需要用到的字型格式 


//設定列寬
