aspose word for java调整表格适应页面宽度

public static void fitTableToPageWidth(Table table) {
    //Get the page settings from the section where the table occurs, as each section can have different page settings.
		Section section = (Section) table.getAncestor(NodeType.SECTION);
    //First run simply gets the table size (the widest row). This is used to calculate the ratio below instead of just each row length

//as the last cell in one row could be shorter than the last cell in the other row. This will preserve these different sizes when fitting.

    //Calculate the width of the page

                //Calculate the ratio of each cell to the row width and then translate this ratio to the page width.
