Summary: [PATCH] removal of invalid row-span attribute values in
table-cells
Key: FOP-2451
URL: https://issues.apache.org/jira/browse/FOP-2451
Project: Fop
Issue Type: Bug
Components: fo/unqualified
Affects Versions: 1.1
Environment: tested on Win7 and Mac OS 10.9
Reporter: Gregor Berg
Fix For: 1.1
Since I have to deal with tables edited in HTML editors which produce invalid
row-span/col-span attributes, I had to work around the row-span validation
error. Thus, this patch tries to recover from the validation error related to a
table-cell trying to span over more rows than its parent provides.
Affected testcases: all four IllegalRowSpanTestCase (no error is thrown,
instead the table is created and can be checked for, e.g., number of rows)
This is a first draft. If the efforts are deemed worthwhile, I would try to
port it to the trunk version.
Recovery process in detail:
As soon as the error condition is encountered, any remaining rows are checked
for PrimaryGridUnits (PGU) - if there are none, it can be assumed that only
empty GridUnits are present (created as fillers to handle the row-span of an
above PGU). Such rows are removed, the corresponding PGUs cope with this
removal by adjusting their pgu.rows and by decreasing the row-span of their
pgu.cell.
Finally, the last valid row encountered resets its borders corresponding to its
modified rowgroup (since this row may now be the last row of a table, its
borders are updated accordingly).
