Set Column Width to Scalable Unit like em or percent with Node.js via C++

Generating an HTML file from a spreadsheet is very common. The size of the columns is defined in “pt,” which works in many cases. However, there can be a case where this fixed size may not be required. For example, if a container panel width is 600px, where this HTML page is being displayed, you may get a horizontal scrollbar if the generated table width is bigger. It was required that this fixed size shall be changed into a scalable unit like em or percent to get a better presentation. Following sample code can be used where HtmlSaveOptions.getWidthScalable() is set to true for creating scalable width.

Sample source file and output files can be downloaded from the following links:

sampleForScalableColumns.xlsx

outsampleForScalableColumns.zip

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// Load sample source file
const dataDir = path.join(__dirname, "data");
const sourceFilePath = path.join(dataDir, "sampleForScalableColumns.xlsx");
const workbook = new AsposeCells.Workbook(sourceFilePath);

// Specify Html Save Options
const options = new AsposeCells.HtmlSaveOptions();

// Set the property for scalable width
options.setWidthScalable(true);

// Specify image save format
options.setExportImagesAsBase64(true);

// Save the workbook in Html format with specified Html Save Options
const outputFilePath = path.join(dataDir, "outsampleForScalableColumns.html");
workbook.save(outputFilePath, options);
