This is my code to add data from datatable to richtextbox on table format
dt = new DataTable();
SQLiteConnection conn = new SQLiteConnection("Data Source=" + folderPath + "\\" + databaseName);
InitializeComponent();
s = MyProperty.ToString();
conn.Open();
SQLiteCommand command = new SQLiteCommand("SELECT id,nameSearch,dt,totalRecords FROM ACCESSDETAILS Where id=" + s + " AND numberSearch IS NULL AND dt BETWEEN '" + datepicker + "' AND '" + datepicker1+ "'", conn);
SQLiteDataAdapter da = new SQLiteDataAdapter(command);
da.Fill(dt);
conn.Close()
var tab = new Table();
var gridLenghtConvertor = new GridLengthConverter();
tab.Columns.Add(new TableColumn() { Name = "ID", IsEnabled = true, Width = (GridLength)gridLenghtConvertor.ConvertFromString("30") });
tab.Columns.Add(new TableColumn() { Name = "Name", IsEnabled = true, Width = (GridLength)gridLenghtConvertor.ConvertFromString("80") });
tab.Columns.Add(new TableColumn() { Name = "Date", IsEnabled = true, Width = (GridLength)gridLenghtConvertor.ConvertFromString("100") });
tab.Columns.Add(new TableColumn() { Name = "TotalRecords", IsEnabled = true, Width = (GridLength)gridLenghtConvertor.ConvertFromString("auto") });
tab.RowGroups.Add(new TableRowGroup());
int i = 0;
foreach (DataRow dr in dt.Rows)
{
tab.RowGroups[0].Rows.Add(new TableRow());
var tabRow = tab.RowGroups[0].Rows[i];
tabRow.Cells.Add(new TableCell(new Paragraph(new Run(dr.ItemArray[0].ToString() + " | "))));
tabRow.Cells.Add(new TableCell(new Paragraph(new Run(dr.ItemArray[1].ToString() + " | "))));
tabRow.Cells.Add(new TableCell(new Paragraph(new Run(dr.ItemArray[2].ToString() + " | "))));
tabRow.Cells.Add(new TableCell(new Paragraph(new Run(dr.ItemArray[3].ToString()))));
i++;
}
rtf.Document.Blocks.Add(tab);
我在这里添加列和列，但该名称无法显示。enter image description here
此图像是我的打印页面，我希望在该页面上将id，名称，日期和总记录作为列名。我想像下面的图像一样围绕它的边框 enter image description here
请帮助我。

创建数据表时可以生成列。请参考以下代码作为您的问题的参考。
//Create datatable
DataTable dt = new DataTable();
//put Your columns Name
dt.Columns.Add("ID", typeof(int));
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Date", typeof(string));
dt.Columns.Add("Total Records", typeof(string));
//Your Query Code
SQLiteConnection conn = new SQLiteConnection("Data Source=" + folderPath + "\\" + databaseName);
InitializeComponent();
s = MyProperty.ToString();
conn.Open();
SQLiteCommand command = new SQLiteCommand("SELECT id,nameSearch,dt,totalRecords FROM ACCESSDETAILS Where id=" + s + " AND numberSearch IS NULL AND dt BETWEEN '" + datepicker + "' AND '" + datepicker1+ "'", conn);
SQLiteDataAdapter da = new SQLiteDataAdapter(command);
ds = new DataSet();
da.Fill(ds);
#Fill Dataset values in Datatable rows
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
DataRow dr = dt.NewRow();
dr[0] =Convert.ToInt32( ds.Tables[0].Rows[i]["id"]);
dr[1] = ds.Tables[0].Rows[i]["namesearch"].ToString() + " " + ds.Tables[0].Rows[i]["lastname"].ToString();
dr[2] = ds.Tables[0].Rows[i]["dt"].ToString();
dr[3] = ds.Tables[0].Rows[i]["totalRecords"].ToString();
dt.Rows.Add(dr);
}
conn.Close() ;
#For Print Datatable
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == true)
{
FlowDocument fd = new FlowDocument();
Table table = new Table();
TableRowGroup tableRowGroup = new TableRowGroup();
TableRow r = new TableRow();
fd.PageWidth = printDialog.PrintableAreaWidth;
fd.PageHeight = printDialog.PrintableAreaHeight;
fd.BringIntoView();
fd.TextAlignment = TextAlignment.Center;
fd.ColumnWidth = 500;
table.CellSpacing = 0;
for (int j = 0; j < dt.Columns.Count; j++)
{
r.Cells.Add(new TableCell(new System.Windows.Documents.Paragraph(new Run(dt.Columns[j].ToString()))));
r.Cells[j].ColumnSpan = 4;
r.Cells[j].Padding = new Thickness(4);
r.Cells[j].BorderBrush = Brushes.Black;
r.Cells[j].FontWeight = FontWeights.Bold;
r.Cells[j].Background = Brushes.DarkGray;
r.Cells[j].Foreground = Brushes.White;
r.Cells[j].BorderThickness = new Thickness(1, 1, 1, 1);
}
tableRowGroup.Rows.Add(r);
table.RowGroups.Add(tableRowGroup);
for (int i = 0; i < dt.Rows.Count; i++)
{
var gv = dt.Rows[i];
tableRowGroup = new TableRowGroup();
r = new TableRow();
for (int j = 0; j < gv.ItemArray.Length; j++)
{
r.Cells.Add(new TableCell(new System.Windows.Documents.Paragraph(new Run(gv.ItemArray[j].ToString()))));
r.Cells[j].ColumnSpan = 4;
r.Cells[j].Padding = new Thickness(4);
r.Cells[j].BorderBrush = Brushes.Black;
r.Cells[j].Background = Brushes.White;
r.Cells[j].Foreground = Brushes.Black;
r.Cells[j].BorderThickness = new Thickness(1, 1, 1, 1);
}
tableRowGroup.Rows.Add(r);
table.RowGroups.Add(tableRowGroup);
}
fd.Blocks.Add(table);
printDialog.PrintDocument(((IDocumentPaginatorSource) fd).DocumentPaginator, "");
}
