C＃FlowDocument单元格宽度问题

Question

我无法为添加到flowdocument的每行添加单元格。我想手动设置流文档单元格的宽度。此代码是采取和修改从Microsoft example

代码：

internal static FlowDocument GetPicklistFlowDoc() 
    { 
     DataTable daTable = new DataTable(); 
     using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["PicklistConnection"].ConnectionString)) 
     using (var cmd = new SqlCommand("GetCurrentPicklistItems", con)) 
     using (var da = new SqlDataAdapter(cmd)) 
     { 
      cmd.CommandType = CommandType.StoredProcedure; 
      da.Fill(daTable); 
     } 

     FlowDocument flowDoc = new FlowDocument(); 
     flowDoc.IsColumnWidthFlexible = true; 
     // Create the Table... 
     Table table1 = new Table(); 

     // ...and add it to the FlowDocument Blocks collection. 
     flowDoc.Blocks.Add(table1); 


     // Set some global formatting properties for the table. 
     //table1.CellSpacing = 15; 
     //table1.Background = Brushes.White; 

     int numberOfColumns = 6; 

     // Create and add an empty TableRowGroup to hold the table's Rows. 
     table1.RowGroups.Add(new TableRowGroup()); 

     // Add the first (title) row. 
     table1.RowGroups[0].Rows.Add(new TableRow()); 

     // Alias the current working row for easy reference. 
     TableRow currentRow = table1.RowGroups[0].Rows[0]; 

     // formatting for the title row. 
     currentRow.Background = Brushes.Silver; 
     currentRow.FontSize = 24; 
     currentRow.FontWeight = System.Windows.FontWeights.Bold; 

     // Add the header row with content, 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Picklist" + DateTime.Now.ToString())))); 
     // and set the row to span all 6 columns. 
     currentRow.Cells[0].ColumnSpan = 6; 

     // Add (header) row. 
     table1.RowGroups[0].Rows.Add(new TableRow()); 
     currentRow = table1.RowGroups[0].Rows[1]; 

     // formatting for the header row. 
     currentRow.FontSize = 18; 
     currentRow.FontWeight = FontWeights.Bold; 


     // Add cells with content to the second row. 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Code")))); 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Qty")))); 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Location")))); 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Last 1")))); 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Issue")))); 
     currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Store")))); 
     currentRow.Cells[0].ColumnSpan = numberOfColumns; 
     //currentRow.Cells[0].BorderThickness = new Thickness(0, 0, 0, 1); 
     //currentRow.Cells[0].BorderBrush = Brushes.Black; 

     // Add the another row. and formatting 
     table1.RowGroups[0].Rows.Add(new TableRow()); 
     currentRow = table1.RowGroups[0].Rows[2];     
     currentRow.FontSize = 14; 
     currentRow.FontWeight = FontWeights.Normal; 
     currentRow.FontFamily = new FontFamily("Arial"); 
     int z = 3; 

     foreach (DataRow dataRow in daTable.Rows) 
     { 
      double quantity = (double)dataRow[1]; 
      string location = dataRow[3].ToString(); 


       if (quantity > 1) 
       { 

        currentRow.Background = Brushes.Silver; 

        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[0].ToString())))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[1].ToString())))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(location)))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run("")))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run("")))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[2].ToString())))); 

        currentRow.Cells[0].ColumnSpan = numberOfColumns; 

        for (int i = 0; i <= numberOfColumns - 1; i++) 
        { 

         currentRow.Cells[i].BorderThickness = new Thickness(1, 1, 1, 1); 
         currentRow.Cells[i].BorderBrush = Brushes.Black; 
        } 



       } 
       else 
       { 
        //currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[0].ToString())))); 

        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[0].ToString())))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[1].ToString())))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[3].ToString())))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run("")))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run("")))); 
        currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dataRow[2].ToString())))); 
        currentRow.Cells[0].ColumnSpan = numberOfColumns; 
        for (int i = 0; i <= numberOfColumns - 1; i++) 
        { 

         currentRow.Cells[i].BorderThickness = new Thickness(1, 1, 1, 1); 
         currentRow.Cells[i].BorderBrush = Brushes.Black; 
        } 

       } 

      table1.RowGroups[0].Rows.Add(new TableRow()); 
      currentRow = table1.RowGroups[0].Rows[z]; 

      location = ""; 

      z++; 
     } 


     z = 3; 


     return flowDoc; 
    } 

我想手动设置单元格宽度属性或者将它们设置为autoWidth。

找到answer后张贴在相关的问题栏。

GridLengthConverter glc = new GridLengthConverter(); 
table.Columns[0].Width = (GridLength)glc.ConvertFromString("300"); 
table.Columns[1].Width = (GridLength)glc.ConvertFromString("50"); 
table.Columns[2].Width = (GridLength)glc.ConvertFromString("50");
