本文介绍如何使用Spire.Presentation for Java设置幻灯片中的表格的对齐方式。

import com.spire.presentation.FileFormat;
import com.spire.presentation.ITable;
import com.spire.presentation.Presentation;
import com.spire.presentation.ShapeAlignmentEnum;

public class AlignTable {

    public static void main(String[] args) throws Exception {

        //创建Presentation对象
        Presentation presentation = new Presentation();

        //加载示例文档
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pptx");

        //声明ITable变量
        ITable table = null;

        //遍历第一个幻灯片中的图形
        for (Object shape: presentation.getSlides().get(0).getShapes()
        ) {

            //判断图形是否为ITable对象
            if (shape instanceof ITable)
            {
                //将图形转换为ITable对象
                table =(ITable)shape;
            }
        }

        //将表格水平居中
        table.setShapeAlignment(ShapeAlignmentEnum.ShapeAlignment.AlignCenter);

        //将表格垂直居中
        table.setShapeAlignment(ShapeAlignmentEnum.ShapeAlignment.AlignMiddle);

        //保存文档
        presentation.saveToFile("AlignTable.pptx", FileFormat.PPTX_2013);
    }
}
