使用WordArt为电子表格添加特殊文本效果，例如，将标题横跨文件顶部，装饰文本，并使文本适应预设形状，或将文本应用于Excel工作表作为背景水印。 WordArt成为您可以在电子表格中移动或定位以添加装饰的对象。
以下示例显示如何添加文字艺术形状以设置工作表的背景水印。
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiate a new Workbook
const workbook = new AsposeCells.Workbook();
// Get the first default sheet
const sheet = workbook.getWorksheets().get(0);
// Add Watermark
const wordart = sheet.getShapes().addTextEffect(AsposeCells.MsoPresetTextEffect.TextEffect1,
"CONFIDENTIAL", "Arial Black", 50, false, true, 18, 8, 1, 1, 130, 800);
// Get the fill format of the word art
const wordArtFormat = wordart.getFill();
// Set the transparency
wordArtFormat.setTransparency(0.9);
// Make the line invisible
const lineFormat = wordart.getLine();
const outputFilePath = path.join(dataDir, "Watermark_Test.out.xls");
// Save the file
workbook.save(outputFilePath);
