[xep-support] display-align problems

[Alexander Peshkov]

Hello Wick,

In your example you have table with only one table cell without any
dimensions specified. In such a case table will shrink to minimum necessary
size to accommodate it's content. display-align would not have
any effect since where is no empty space in block progression
dimension. In this particular case 'centering' effect is just a result
of placement 9pt high text in 50pt high line.
I suppose you wanted to have 50pt high table cell with 9pt high text
aligned at the bottom. To achieve this you should wrap you fo:table-cell
in fo:table-row with height="50pt" instead of line-height. Take a
look at example below:

<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
       <fo:layout-master-set>
             <fo:simple-page-master master-name="test-master" >
                    <fo:region-body region-name="region-body"/>
             </fo:simple-page-master>
       </fo:layout-master-set>
       <fo:page-sequence master-reference="test-master">
             <fo:flow flow-name="region-body">
                    <fo:table font-size="9pt">
                           <fo:table-body>
                                 <fo:table-row height="50pt">
                                         <fo:table-cell display-align="after" border="1.0pt solid black">
                                                <fo:block>
                                                          I expect this text to appear
                                                          at the bottom of the cell.
                                                </fo:block>
                                         </fo:table-cell>
                                 </fo:table-row>
                           </fo:table-body>
                    </fo:table>
             </fo:flow>
       </fo:page-sequence>
</fo:root>

Hope this helps.

Best regards,

WS> The  book "XSL-FO" published by O'Reilly instructs that to align text in
WS> the bottom of a table cell I should specify the following cell
WS> attribute:
WS>      display-align="after"
 
WS> I've tried this and no matter what value I specify for the
WS> "display-align" attribute, my text is always vertically centered  The
WS> XEP spec sheet shows that display-align is supported so please let me
WS> know if this is not what "display-align" does or if I am somehow
WS> mis-using it.
WS> I will include an example below.
