Как сохранить HTML-таблицы правильно выровненными при рендеринге в PDF?

---

Я хочу, чтобы html-таблицы были правильно выровнены при рендеринге в PDF с помощью Itextsharp. Содержимое таблицы идет вертикально, а не горизонтально для 2 таблиц слева и справа и так далее при рендеринге в формате PDF.

Ниже приведен мой html-код:

<div style="width: 760px">
        
    <table width="760px"><tbody><tr><td align="center">
             <asp:Panel ID="pnlGridExport" runat="server" Width="820px" Visible="false">
            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px; float: left" align="left"><tbody><tr><td colspan="2" style="height: 18px; color: black">
                        Outward
                    </td></tr><tr><td>No: of OCEs</td><td><asp:Label ID="lblOCECount" runat="server"></td></tr><tr><td>Amount</td><td><asp:Label ID="lblOCEAmount" runat="server"></td></tr><tr><td style="color: blue">CR</td></tr></tbody></table>
            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px; float: right" align="right"><tbody><tr><td colspan="2" style="height: 18px; color: black">
                        Inward</td></tr><tr><td>No: of ICEs</td><td><asp:Label ID="lblICECount" runat="server"></td></tr><tr><td>Amount</td><td><asp:Label ID="lblICEAmount" runat="server"></td></tr><tr><td style="color: red">DR</td></tr></tbody></table>
              
            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px; float: left" align="left"><tbody><tr><td colspan="2" style="height: 18px; color: black">
                        Outward
                    Return</td></tr><tr><td>No: of IREs</td><td><asp:Label ID="lblIRECount" runat="server"></td></tr><tr><td>Amount</td><td><asp:Label ID="lblIREAmount" runat="server"></td></tr><tr><td style="color: red">DR</td></tr></tbody></table>
            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px; float: right" align="right"><tbody><tr><td colspan="2" style="height: 18px; color: black">

            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px; float: left" align="left"><tbody><tr><td colspan="2" style="height: 18px; color: black">
                        Net of Outward</td></tr><tr><td>No: of Recods</td><td><asp:Label ID="lblNetOutwardRecords" runat="server"></td></tr><tr><td>Amount</td><td><asp:Label ID="lblNetOutwardAmount" runat="server"></td></tr><tr><td style="color: blue">CR</td></tr></tbody></table>
            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px; float: right" align="right"><tbody><tr><td colspan="2" style="height: 18px; color: black">

            <table border="1" style="font-family: Arial; font-size: 10pt; width: 400px" align="center"><tbody><tr><td colspan="2" style="height: 18px; color: black">
                        Net Amount</td><td colspan="2" style="height: 18px; color: black">
                       <asp:Label ID="lblNetAmount" runat="server"></td></tr></tbody></table>
            </td></tr></tbody></table>
</div>

Что я уже пробовал:

Я рендеринг PDF-файла через itextsharp dll. Код для рендеринга того же самого в PDF выглядит следующим образом:

#region View PDF Report
/// <summary>
/// populate the report using the search criteria.
/// 
private void ViewPDFReport()
{
    try
    {

        BLL_MISReports objMisReport = new BLL_MISReports();
        DateTime FromDate = DateTime.ParseExact(txtFromDate.Value.Trim(), "dd/MM/yyyy", CultureInfo.InvariantCulture);
        DateTime ToDate = DateTime.ParseExact(txtToDate.Value.Trim(), "dd/MM/yyyy", CultureInfo.InvariantCulture);
        DataSet ds = objMisReport.BusinessDaySettlementReport(FromDate, ToDate, Convert.ToInt32(Session["USER"].ToString()));

        DataTable dt = new DataTable();
        if (ds.Tables[0].Rows.Count > 0)
        {
            dt = ds.Tables[0];
            pnlGridExport.Visible = true;
            //Bind Datatable to Labels
            lblOCECount.Text = dt.Rows[0]["OCERecordCount"].ToString();
            lblOCEAmount.Text = dt.Rows[0]["OCEAmount"].ToString();

            lblNetInwardAmount.Text = dt.Rows[0]["NetInWardAmount"].ToString();
