Ampersands in table cells cause strange spacing #51

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
Make a table cell with an ampersand in the text, i.e <td>yes & no</td>

What is the expected output? What do you see instead?
Should get a table cell with "yes & no":

STARTTAG td {}
box_shadow 77.0487623762 5.50333333333 None
td cell 35.6841707921 77.0487623762 yes & no L  *
ENDTAG td

But instead each word gets its own table cell:

STARTTAG td {}
box_shadow 77.0487623762 5.50333333333 None
td cell 35.6841707921 77.0487623762 yes L  *
box_shadow 77.0487623762 5.50333333333 None
td cell 112.732933168 77.0487623762 & *
box_shadow 77.0487623762 5.50333333333 None
td cell 189.781695545 77.0487623762  no *
ENDTAG td

This is easily fixed by preformatting the html code: 
After you open and read the html code into a variable like this

    with open(infile,'r') as f: 
        text = f.read(-1)
you add this (you will need "import re"):
    text = re.sub('&','@amp',text)

Now in the handle_data method in the Class HTML2FPDF(HTMLParser) you add this 
line at the very beginning of the method:
    txt = re.sub('@amp','&',txt)

And the problem is solved. The problem is caused by the entityref method not 
being implemented

Seems to be the same as described in Issue 80, also affecting other special 
markup in table cells.
