I’ve modified my DITA PDF and xhtml publishing scripts to read an
attribute (bg_color) from colspec, row, and entry elements and reflect
the defined color in the output. Now I am working on the GUI for this.
In the CSS presentation layer for XMLmind, it was quite easy to write
commands to set the colors on the elements, and easy to make the
interface reflect the color chosen when the attribute is set at the
entry or row level. Making a whole column in a table reflect a color
selection made on its colspec element, however, is proving difficult. I
would prefer to do this in CSS somehow rather than writing a command to
actually add the bg_color attribute to every individual entry in the
column, partly because this would involve having to re-apply it every
time I added a new row.
Are there any widgets in XMLmind that connect entry elements with their
colspec elements? The xpath statement for intelligently reaching
backwards from each entry element and finding the right colspec element
is proving to be problematical.
--> It's not a widget. It's a CSS stylesheet extension (which must be
coded in Java) called "StyleSpecs".
The StyleSpecs you need computes the background color of an entry based
on the bg_color attribute of the entry itself, its parent row, its
colspec element (you'll define the lookup order you prefer).

--> The XHTML configuration has an implementation of StyleSpecs which
does this for style="background-color: XXX; background-image: YYY;" of
the cols and colgroups corresponding to a td or th.
The relevant .java files are:
* src/com/xmlmind/xmleditext/xhtml/table/StyleSpecsImpl.java
* src/com/xmlmind/xmleditext/xhtml/table/TableSupport.java (registers
StyleSpecsImpl with the CSS engine)
The implementation for XHTML is a bit complicated because it needs to
access the CSS style of an element. What you want, based on the value of
attribute bg_color, should be much easier to implement.
