Table cell Text is not left aligned when using insertHtml method

I have used the InsertHtml method of aspose word for mail merge, Where I am making on td (table cell) text centered but other cell text should be left-aligned, but all table cell text are left aligned.
The HTML used is

<html>
<body>
    <table style="font:calibri;font-size:7pt;border:none;">
        <td style="border:none;">
            <table style="border:1pt solid black;font:calibri;font-size:7pt;margin-left:15pt;width:155pt;margin-bottom:15pt;">
                <tr style="background-color:#d9d9d9;border:1pt solid black;height:20pt;">
                    <td colspan="2" style="text-align:center;border-bottom:1pt solid black;border-right:1pt solid black;"><b>Interviewer</b></td>
                </tr>
                <tr style="border:1pt solid black;height:30pt;">
                    <td colspan="2" style="border-bottom:1pt solid black;border-right:1pt solid black;">
                    </td>
                </tr>

            </table>
        </td></tr>
        <tr></tr>
        <tr>
    </table>
</body>
</html>

after mail merge all cell text is centered but actually only the cell where text-align:centered is set that cell should be centered rest should be left aligned.

@SachinSingh Could you please also attach your sample template and problematic output here for our reference? I have tested your HTML with the following simple code:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertHtml(File.ReadAllText(@"C:\Temp\in.html"));
doc.Save(@"C:\Temp\out.docx");

Alignment in cells is correct: out.docx (8.0 KB)

In your output also the right border is missing in all tables, in my output right border is there, but texts within tds are not left-aligned.
As you can see in my output Name and JobTitle are not left-aligned , can you please test and give a work around on 21.3 version.

@SachinSingh I have tested the scenario using the code provided above and 21.3 version of Aspose.Words - the output is the same as using 23.9 version. Here are DOCX documents produced on my side using 21.3 version of Aspose.Words and using MS Word 2019:
ms.docx (13.0 KB)
out12.3.docx (8.1 KB)
