您可能已经解决了。但是对于寻找答案的其他人，这是我所做的：

检查ITableCellOptions.width.WidthType以获得更多选项

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 })],
    });
  }),
});
