本文将介绍如何使用Spire.PDF删除PDF Grid中的行和列。

//创建PdfDocument实例
PdfDocument doc = new PdfDocument();

//添加一页
PdfPageBase page = doc.Pages.Add();

//创建PDF grid
PdfGrid grid = new PdfGrid();

//设置单元格内容和边框之间的距离
grid.Style.CellPadding = new PdfPaddings(3, 3, 1, 1);

//添加3行和4列
PdfGridRow row1 = grid.Rows.Add();
PdfGridRow row2 = grid.Rows.Add();
PdfGridRow row3 = grid.Rows.Add();
grid.Columns.Add(4);

//设置列宽
foreach (PdfGridColumn column in grid.Columns)
{
    column.Width = 60f;
}

//写入数据到单元格
for (int i = 0; i < grid.Columns.Count; i++)
{
    row1.Cells[i].Value = String.Format("column{0}", i + 1);
    row2.Cells[i].Value = "a";
    row3.Cells[i].Value = "b";
}

//删除第二行
grid.Rows.RemoveAt(1);

//删除第二列
grid.Columns.RemoveAt(1);

//在页面的指定位置绘制grid
grid.Draw(page, new PointF(0, 20));

//保存文件
doc.SaveToFile("Output.pdf");

'创建PdfDocument实例
Dim doc As New PdfDocument()

'添加一页
Dim page As PdfPageBase = doc.Pages.Add()

'创建PDF grid
Dim grid As New PdfGrid()

'设置单元格内容和边框之间的距离
grid.Style.CellPadding = New PdfPaddings(3, 3, 1, 1)

'添加3行和4列
Dim row1 As PdfGridRow = grid.Rows.Add()
Dim row2 As PdfGridRow = grid.Rows.Add()
Dim row3 As PdfGridRow = grid.Rows.Add()
grid.Columns.Add(4)

'设置列宽
For Each column As PdfGridColumn In grid.Columns
	column.Width = 60F
Next

'写入数据到单元格
For i As Integer = 0 To grid.Columns.Count - 1
	row1.Cells(i).Value = [String].Format("column{0}", i + 1)
	row2.Cells(i).Value = "a"
	row3.Cells(i).Value = "b"
Next

'删除第二行
grid.Rows.RemoveAt(1)

'删除第二列
grid.Columns.RemoveAt(1)

'在页面的指定位置绘制grid
grid.Draw(page, New PointF(0, 20))

'保存文件
doc.SaveToFile("Output.pdf")
