全部折叠本文展示了如何为表格中的特定单元格添加背景色。同时，也展示了如何利用TableCell.CellStyle属性来设置用来渲染表格的样式。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了如下代码
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 SubC#
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(); } - 将表格的宽和高都设为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#
C# 拷贝代码table.Width = new C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm);
- 在上一步骤的代码后面追加如下代码。这些代码将会为第一行第二列的单元格添加深红色的背景色。
Visual Basic
Visual Basic 拷贝代码table.Cells(1, 2).CellStyle.BackColor = Color.Crimson
C#
C# 拷贝代码table.Cells[1, 2].CellStyle.BackColor = Color.Crimson;
注意：这里的行和列都是从0开始计数。上述代码使用TableCell.CellStyle 属性来设置单元格的样式 - 为第0行第一列的单元格添加蓝紫色的背景色。输入如下代码：
Visual Basic
Visual Basic 拷贝代码table.Cells(0, 1).CellStyle.BackColor = Color.BlueViolet
C#
C# 拷贝代码table.Cells[0, 1].CellStyle.BackColor = Color.BlueViolet;
运行程序看一下:
你的表格应该看起来跟下面的表格类似:
