#1383 XSL-FO: `<table rowheader="firstcol">` selects wrong header cell when used with `<entry morerows>`

[Nutchanon Wetchasit]

I ran into an issue in current DocBook XSL-FO stylesheet when I was trying to use a column-based table heading in a table that some first-column cell span several rows, like follows:

<informaltable rowheader="firstcol">
    <tgroup cols="2">
        <tbody>
            <row><entry>Row 1 header</entry><entry>Row 1 data</entry></row>
            <row><entry morerows="2">Row 2-4 header</entry><entry>Row 2 data</entry></row>
            <row><entry>Row 3 data</entry></row>
            <row><entry>Row 4 data</entry></row>
        </tbody>
    </tgroup>
</informaltable>

The expected result is:

Row 1 header	Row 1 data
Row 2-4 header	Row 2 data
	Row 3 data
	Row 4 data

But the actual generated result is like:

Row 1 header	Row 1 data
Row 2-4 header	Row 2 data
	Row 3 data
	Row 4 data

It seems that the FO stylesheet gives the heading cell style to the first <entry> element found in each <row>, without considering if the first column was already occupied by a row-spanning cell declared from previous row. Both <table> and <informaltable> are affected.

Please note that DocBook HTML stylesheet is not affected by this issue (though it was affected in past releases like 1.77.1).

Test Docbook XML files, generated XSL-FO intermediate, output PDF file, reference HTML rendering of both <informaltable> and <table> case, and build output are attached as xslfo-table-vheaderspan.zip.

Thanks for the report. I checked and indeed the template does not take into account morerows. It just applies the bold to the first entry in each row. Fixing this is a bit more tricky because the template has to keep track of such spans. I'll try to fix it before the next release.
