Question

我尝试使用iTextSharp查看PDF文件中的表格。我已经弄明白了如何添加表格，并通过单击按钮打开PDF文件，但表格字体太大，文字被包裹起来使它们难以阅读。我已输入此代码，但表格字体没有任何反应。

    public partial class selectedorderForm : Form
    {
        public selectedorderForm(string strValue)
        {
            InitializeComponent();
            textBox1.Text = strValue;

        }
        DataTable dt;
        private void selectedorderForm_Load(object sender, EventArgs e)
        {
            SqlCeConnection con = new SqlCeConnection(@"Data Source=|DataDirectory|\LWADataBase.sdf;");
            SqlCeDataAdapter sda = new SqlCeDataAdapter("select * from orderTBL ", con);

            dt = new DataTable();
            sda.Fill(dt);
            dataGridView1.DataSource = dt;
            DataView dv = new DataView(dt);
            dv.RowFilter = "[Order Number] like '%" + textBox1.Text.Trim() + "%'";
            dataGridView1.DataSource = dv;
        }

        private void pdfBTN_Click(object sender, EventArgs e)

            iTextSharp.text.Font fontTitle = FontFactory.GetFont("Arial", 18, iTextSharp.text.Font.BOLD, BaseColor.BLACK);


            Document doc = new Document(iTextSharp.text.PageSize.A4, 10, 10, 10, 10);


            PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream("PurchaseOrder-"+textBox1.Text+".pdf", FileMode.Create));
            doc.Open();


            Paragraph title = new Paragraph("PURCHASE ORDER " + textBox1.Text +"\n Lewis Warby Airbrushing\n", fontTitle);
            title.Alignment = Element.ALIGN_CENTER;
            doc.Add(title);

            title.SpacingAfter = 15f;







            iTextSharp.text.Font fontTable = FontFactory.GetFont("Arial", 5, iTextSharp.text.Font.NORMAL, BaseColor.BLACK);

            PdfPTable table = new PdfPTable(dataGridView1.Columns.Count);
            table.SpacingBefore = 45f;
            table.TotalWidth = 216f;
            table.DefaultCell.Phrase = new Phrase() { Font = fontTable };

            for (int j = 0; j < dataGridView1.Columns.Count; j++)
            {
                table.AddCell(new Phrase(dataGridView1.Columns[j].HeaderText));

            }

            table.HeaderRows = 1;

                    if (dataGridView1[k, i].Value != null)
                    {
                        table.AddCell(new Phrase(dataGridView1[k, i].Value.ToString()));
                    }
                }
            }



            doc.Add(table);




            doc.Close();

            System.Diagnostics.Process.Start("PurchaseOrder-"+textBox1.Text+".pdf");


        }
    }
}

尝试向Phrase构造函数添加字体：

for (int j = 0; j < dataGridView1.Columns.Count; j++)
{
    table.AddCell(new Phrase(dataGridView1.Columns[j].HeaderText,fontTable));

}

//..

for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
    for (int k = 0; k < dataGridView1.Columns.Count; k++)
    {
         if (dataGridView1[k, i].Value != null)
         {
              table.AddCell(new Phrase(dataGridView1[k, i].Value.ToString(),fontTable));
         }
     }
}
