Answer 1

如果您只是在寻找HTML标头标签，那么您可能希望使用TH元素，类似于以下内容：

<TABLE BORDER='1'>
<TR><TH>Table Header 1</TH><TH>Table Header 2</TH></TR>
<TR><TD>Table Cell 1</TD><TD>Table Cell 2</TD></TR>
</TABLE>

如果没有进一步的信息，我们无法在这里提供太多的输入 - 我们需要预期的输入/输出，此时我们只能假设。

    private void btnSend_Click(object sender, EventArgs e)
    {
        string mailBody = "<HTML><Head><Body><table width='100%' style='border:Solid 1px Black;'>";

        foreach (DataGridViewColumn Column in dataGridView3.Columns)
        {
            mailBody += "<td style=font -size:100%'><b>" + Column.HeaderText + "</b></td>";
        }
            foreach (DataGridViewRow row in dataGridView3.Rows)
            {
                mailBody += "<tr style=font - size:150 % '>";
                foreach (DataGridViewCell cell in row.Cells)
                {
                    mailBody += "<td style='color:black;'>" + cell.Value + "</td>";
                }
                mailBody += "</tr>";
            }
        mailBody += "</Head></table></Body></HTML>";

        Outlook._Application _app = new Outlook.Application();
        Outlook.MailItem mail = (Outlook.MailItem)_app.CreateItem(Outlook.OlItemType.olMailItem);

        try
        {
            mail.To = txtTo.Text;
            mail.Subject = txtSubject.Text;
            mail.HTMLBody=mailBody;

            mail.Importance = Outlook.OlImportance.olImportanceNormal;
            ((Outlook._MailItem)mail).Send();
            MessageBox.Show("Your Message has been successfully sent.", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
            txtTo.Clear();
            txtSubject.Clear();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Message", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }
