您可以直接在元素上设置属性Block：

var brushConverter = new BrushConverter();

var tableBorderBrush = brushConverter.ConvertFrom("#CCCCCC");

tableBorderBrush.Freeze();

var headerCellBorderBrush = brushConverter.ConvertFrom("#FFFFFF");

headerCellBorderBrush.Freeze();

private void drawLogTable() 

{

  Table oTable = new Table() { BorderThickness = new Thickness(1), BorderBrush = tableBorderBrush }

  // Add the header row with content,

  currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Date time"))) { BorderThickness = new Thickness(0, 1, 0, 0), BorderBrush = headerCellBorderBrush });

  currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Directory"))) { BorderThickness = new Thickness(0, 1, 0, 0), BorderBrush = headerCellBorderBrush });

  currentRow.Cells.Add(new TableCell(new Paragraph(new Run("File"))) { BorderThickness = new Thickness(0, 1, 0, 0), BorderBrush = headerCellBorderBrush });

  // Read file and add rows

  ...

  foreach (string line in existingFoldersArray)

  {

    ...

    // Add new row

    oTable.RowGroups[0].Rows.Add(new TableRow());

    currentRow = oTable.RowGroups[0].Rows[countLines];

    ...

    //Add the row's cells with their borders set

    currentRow.Cells.Add(new TableCell(new Paragraph(new Run(dateTime))) { BorderThickness = new Thickness(0, 0, 0, 1), BorderBrush = tableBorderBrush });

    currentRow.Cells.Add(new TableCell(new Paragraph(new Run(directory))) { BorderThickness = new Thickness(0, 0, 0, 1), BorderBrush = tableBorderBrush });

    currentRow.Cells.Add(new TableCell(new Paragraph(new Run(file))) { BorderThickness = new Thickness(0, 0, 0, 1), BorderBrush = tableBorderBrush });

    ...

  }

  ...

}

行的边框是单元格的边框。要设置行的边框，TableCell必须设置每行的边框。

我强烈建议使用 XAML 来DataTemplates完成此任务。这更容易、更易读、更容易理解并且更灵活。您还可以使用 XAML 设计器的所见即所得功能。
