添加行和列

import com.spire.presentation.*;

public class AddRowAndColumn {

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

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

        //获取表格
        ITable table = null;
        for (Object shape : presentation.getSlides().get(0).getShapes()) {
            if (shape instanceof ITable) {
                table = (ITable) shape;

                //将最后一行作为新行添加到表格下方
                int rowCount = table.getTableRows().getCount();
                TableRow row = table.getTableRows().get(rowCount - 1);
                table.getTableRows().append(row);

                //获取新行，并设置每个单元格的文本
                rowCount = table.getTableRows().getCount();
                row = table.getTableRows().get(rowCount - 1);
                row.get(0).getTextFrame().setText("美国");
                row.get(1).getTextFrame().setText("华盛顿");
                row.get(2).getTextFrame().setText("北美洲");
                row.get(3).getTextFrame().setText("9372610");

                //将最后一列作为新列添加到表格右方
                int colCount = table.getColumnsList().getCount();
                TableColumn column =table.getColumnsList().get(colCount-1);
                table.getColumnsList().add(column);

                //获取新列，并设置每个单元格的文本
                colCount = table.getColumnsList().getCount();
                column = table.getColumnsList().get(colCount-1);
                column.get(0).getTextFrame().setText("人口");
                column.get(1).getTextFrame().setText("32370000");
                column.get(2).getTextFrame().setText("7350000");
                column.get(3).getTextFrame().setText("15040000");
                column.get(4).getTextFrame().setText("26500000");
                column.get(5).getTextFrame().setText("329740000");
            }
        }

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

删除行和列

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

public class DeleteRowAndColumn {

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

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

        //获取表格
        ITable table = null;
        for (Object shape : presentation.getSlides().get(0).getShapes()) {
            if (shape instanceof ITable) {
                table = (ITable) shape;

                //删除第二列
                table.getColumnsList().removeAt(1, false);

                //删除第二行
                table.getTableRows().removeAt(1, false);
            }
        }

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