本篇將分享如何導(dǎo)出如上圖供貨清單的代碼實例

第一步：下載LibXL類庫

點擊這里下載

第二步：新建項目并引入

#include "libxl.h"
#include <sstream>

using namespace libxl;

Book* book = xlCreateBook();

   int logoId = book->addPicture(L"logo.png");

   // 字體預(yù)設(shè)，包含字號、字色等，可以提前定義幾個

   font10->setSize(10);
   
   // 格式預(yù)設(shè)，比如對齊、文本格式、邊框格式等

   Format* textFormat = book->addFormat();
   textFormat->setFont(textFont);

   Format* borderFormat = book->addFormat(textFormat);
   borderFormat->setBorder();
   borderFormat->setBorderColor(COLOR_GRAY25);
   borderFormat->setAlignV(ALIGNV_CENTER);

   Format* percentFormat = book->addFormat(borderFormat);
   percentFormat->setNumFormat(book->addCustomNumFormat(L"#%_)"));
   percentFormat->setAlignH(ALIGNH_RIGHT);

   Format* textRightFormat = book->addFormat(textFormat);
   textRightFormat->setAlignH(ALIGNH_RIGHT);
   textRightFormat->setAlignV(ALIGNV_CENTER);

   Format* thankFormat = book->addFormat();
   thankFormat->setFont(font10);

      for(int col = 0; col < 3; ++col)
      {
         sheet->writeBlank(row, col, borderFormat);
