Mozilla ignores border-collapse if table has cells with overlapping rowspan and
colspan.
Reproducible: Always
Steps to Reproduce:
1: create html with a table with overlapping cells (such as in the sample HTML
code below)
2: Open it in Mozilla browser
Actual Results: Mozilla displays something like that:
+------+------+------+------+
| r1c1 | r1c2 | | r1c4 |
+------+------+-r1c3-+------+
| row 2 | | |
+-------------+------+------+
| r3c1 | r3c2 | r3c3 | r3c4 |
+------+------+------+------+
(notice the borders that are drawn around both spanning cells)
Expected Results: Layout should be something like that:
+------+------+------+------+
| r1c1 | r1c2 | | r1c4 |
+------+------+ r1c3 +------+
| row 2 |
+-------------+------+------+
| r3c1 | r3c2 | r3c3 | r3c4 |
+------+------+------+------+
(borders around spanning cells have 'collapsed')
sample HTML:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head><title>Table Test</title></head>
<body>
<table border=1 cellspacing="0" style="border-collapse: collapse;">
<tr>
<td>r1c1</td><td>r1c2</td>
<td rowspan="2">*r1c3*</td>
<td>r1c4</td>
</tr>
<tr><td colspan="4">row 2</td></tr>
<tr>
<td>r3c1</td>
<td>r3c2</td>
<td>r3c3</td>
<td>r3c4</td>
</tr>
</table>
</body>
</html>

http://www.w3.org/TR/html4/struct/tables.html#h-11.2.6.1 (Cells that span
several rows or columns) explicitly says:
"Defining overlapping cells is an error. User agents may vary in how they handle
this error (e.g., rendering may vary)."
So not only is your example HTML is invalid, the spec explicitly says that
browsers can handle it any way they want....
You're right.
Nevertheless I think that ie behavior in this scenario is more logical.
Perhaps it's good idea to mark it as a feature request then?
Note that without border-collapse both are doing the same thing...
Severity: normal → enhancement
