I am creating an application using electron and react, and I will need to create a Word text document dynamically, I found a great package, DOCX, but I need to create some tables, and I can't set the size of the columns, I need help setting the size of the columns, follows an excerpt from the code, and documentation link /

// eslint-disable-next-line
import { Document, Packer, Paragraph, TextRun, Table, TableRow, TableCell, VerticalAlign, HeadingLevel } from 'docx';
const {dialog} = window.require('electron').remote;
const app = window.require('electron').remote
const fs = app.require('fs');

const doc = new Document();

export default function createDocx(){

    const table = new Table({
        rows: [
            new TableRow({
                children: [
                    new TableCell({
                        children: [new Paragraph({}), new Paragraph({})],
                        verticalAlign: VerticalAlign.CENTER,

You might've already solved it. But for other people looking for an answer, here is what I did:

Check ITableCellOptions.width.WidthType for more options

const columnTitles = ["Title1", "Title2", "Title3"];

const columnTitleRow = new TableRow({
  children: columnTitles.map((title) => {
    return new TableCell({
      // Make all cells the same with over 100% of the available page width
      width: { size: 100 / columnTitles.length, type: WidthType.PERCENTAGE },
      children: [new Paragraph({ text: title })],
    });
  }),
});

For equal cell width you can also set full width on the table itself.

new Table({
  rows: [...],
  width: { size: 100, type: WidthType.PERCENTAGE },
});
