创建表格中行和列的外边框

本文展示了如何利用LineDef 类对行和列添加实线外边框。本文假设你已经有了一个三行三列的表格。

在你的源代码文件中应该已经存在如下代码：

Visual Basic

Visual Basic	拷贝代码
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ' Make a table. Dim table As C1.C1Preview.RenderTable = New C1.C1Preview.RenderTable(Me.C1PrintDocument1) table.Style.GridLines.All = New C1.C1Preview.LineDef(Color.DarkGray) Dim r As Integer = 3 Dim c As Integer = 3 Dim row As Integer Dim col As Integer For row = 0 To r - 1 Step +1 For col = 0 To c - 1 Step +1 Dim celltext As C1.C1Preview.RenderText = New C1.C1Preview.RenderText(Me.C1PrintDocument1) ' Add empty cells. celltext.Text = String.Format("", row, col) table.Cells(row, col).RenderObject = celltext Next Next ' Generate the document. Me.C1PrintDocument1.Body.Children.Add(table) Me.C1PrintDocument1.Generate() End Sub

C#	拷贝代码
private void Form1_Load(object sender, System.EventArgs e) { // Make a table. C1.C1Preview.RenderTable table = new C1.C1Preview.RenderTable(this.c1PrintDocument1); table.Style.GridLines.All = new C1.C1Preview.LineDef(Color.DarkGray); const int r = 3; const int c = 3; for (int row = 0; row < r; ++row) { for (int col = 0; col < c; ++col) { C1.C1Preview.RenderText celltext = new C1.C1Preview.RenderText(this.c1PrintDocument1); celltext.Text = string.Format("", row, col); // Add empty cells. table.Cells[row, col].RenderObject = celltext; } } // Generate the document. this.c1PrintDocument1.Body.Children.Add(table); this.c1PrintDocument1.Generate(); }

向项目中添加如下代码将你表格的宽高都设为15厘米

Visual Basic

Visual Basic	拷贝代码
table.Height = New C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm) table.Width = New C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm)

C#	拷贝代码
table.Height = new C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm); table.Width = new C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm);

往项目中添加如下代码给第三行的边框属性赋上LineDef 类的一个实例对象（注意，我们利用LineDef 类的构造函数指定了新边框的颜色为红色，宽度为2pt）

Visual Basic

Visual Basic	拷贝代码
table.Rows(2).Style.Borders.All = New C1.C1Preview.LineDef("2pt", Color.Red)

C#	拷贝代码
table.Rows[2].Style.Borders.All = new C1.C1Preview.LineDef("2pt", Color.Red);

如下所示，将一个LineDef 类的新实例赋给第一列的边框属性（注意，我们利用LineDef 类的构造函数指定了新边框的颜色为红色，宽度为2pt）

Visual Basic

Visual Basic	拷贝代码
table.Cols(0).Style.Borders.All = New C1.C1Preview.LineDef("6pt", Color.Blue)

C#	拷贝代码
table.Cols[0].Style.Borders.All = new C1.C1Preview.LineDef("6pt", Color.Blue);

运行程序看一下：

运行时，你的边框将会跟下面的表格相似
