Feature request: Table Diff

[wumpz]

Since each cell should be treated like a word isn't that identical to merging all cells to a line and comparing a list of those?

[wise-coders]

Maybe it would work, but the code would be much cleaner and better if would exists a method to compare tables directly.
Isn't it possible to add a such a method to java-diff-utils?

[wumpz]

Could you make a suggestion?

[wise-coders]

If possible, please implement a method to compare a table as list of arrays List<String[]> and return the matching, added, changed and dropped rows. The compare should focus only at the row level.

[wumpz]

Since diffing is a text processing algorithm, I will not implement this. Since you are diffing each cell against each cell you should call the differ for each cell and display this result. However, connecting cells to rows will not work, since the idff algorithm would not preserve cell position for patching.
