How to parse table with rowspan and colspan

Question

First, I have read Parsing a table with rowspan and colspan. I even answered the question. Please read before you mark this as duplicate.

Answer 1

Important to note, that Martijn Pieters solution does not account for the case of cells having rowspan and colspan attribute simultaneosly. E.g.

    

        
A
        
B
        
C
        
D
    
    

        
E
    
    

        
E
        
C
        
C
    
    

        
E
        
C
        
C
        
C
        
C
        
C
    

This table renders to

+-----------+---+---+---+
| A         | B | C | D |
|           +---+---+---+
|           | E         |
|           +---+---+---+
|           | E | C | C |
+---+---+---+---+---+---+
| E | C | C | C | C | C |
+---+---+---+---+---+---+

but if we apply the function we get

[['A', 'A', 'A', 'B', 'C', 'D'],
 ['A', 'E', 'E', 'E', None, None],
 ['A', 'E', 'C', 'C', None, None],
 ['E', 'C', 'C', 'C', 'C', 'C']]

There may be some edge cases, but extending rowspan bookkeeping to cells in the product of rowspan and colspan, i.e.

   for drow, dcol in product(range(rowspan), range(colspan)):
            try:
                table[row + drow][col + dcol] = value
                rowspans[col + dcol] = rowspan
            except IndexError:
                # rowspan or colspan outside the confines of the table
                pass

seems to work on examples in this thread, and for the table above it will output

[['A', 'A', 'A', 'B', 'C', 'D'],
 ['A', 'A', 'A', 'E', 'E', 'E'],
 ['A', 'A', 'A', 'E', 'C', 'C'],
 ['E', 'C', 'C', 'C', 'C', 'C']]
