iTextSharp: Extra space between lines

I am missing something in the following code and I get an extra space between lines in the output

        PdfContentByte ^cb = writer->DirectContent;
        ColumnText ^ct = gcnew ColumnText(cb);

        float gutter = 15;
        float colwidth = (document->Right - document->Left - gutter) / 2;

        array<float, 1>^ left = { document->Left + 133, document->Top - 35,
            document->Left + 133, document->Bottom };
        array<float, 1>^ right = { document->Left + colwidth, document->Top - 35,
            document->Left + colwidth, document->Bottom };

        for (int i = 0; i < m_strTestString->Length; i++)
        {
            Phrase ^Ps = gcnew Phrase(m_strTestString[i], font);
            Ps->SetLeading(0.0f, 0.6f);
            ct->AddText(Ps);
            ct->AddText(Chunk::NEWLINE);
        }
        ct->SetColumns(left, right);
        ct->Go();

The output is as below:

Client Name:sgsfg

Product:hjghj

Estimate#:354

I do not want the space between the above lines.

What am I doing wrong? Any help appreciated

One small clarification, if I do not add the 

    ct->AddText(Chunk::NEWLINE);

the output shows up as:

   Client Name:sgsfgProduct:hjghjEstimate

   #:354

So I do not think my issue is because of the ct->AddText(Chunk::NEWLINE);

Thanks

You should be aware that ColumnText knows two modes of operation, text mode and composite mode.

In text mode you add stuff with AddText and iText(Sharp) arranges the text pieces according to some ColumnText parameters.

In composite mode you add stuff using AddElement and iText(Sharp) arranges the elements according to the parameters they bring along.

Text mode has the advantage that it supports irregular (not necessarily rectangular) columns but essentially only supports text.

Composite mode has the advantage that it supports different kinds of elements (Paragraph, List, PdfPTable, and Image instances) but only supports rectangular columns.

In your case only text is added using only setText calls. Thus, you are in text mode. So the text is arranged according to ColumnText parameters. As you meanwhile (while I wrote my answer) have discovered yourself, you therefore have to use

ct->SetLeading(0.0f, 0.6f);

instead of

Ps->SetLeading(0.0f, 0.6f);

I figured it out

Instead of 

Ps->SetLeading(0.0f, 0.6f);

I need to do 

ct->SetLeading(0.0f, 0.6f);
