comment Splitting a polynomial into sum of factors, not necessarily linear
What you want is not really factorization, because that's about multiplication of factors. There's an infinity of terms that can be added to arrive at the same result. But have a look at Factor anyway.

Alternatively, you might like to explore the undocumented and not entirely stable TableView[]

comment Manipulate: SEIR model
To explain Sektor's remark you have an = instead of == in e[0] = e0. The error message could have given you a clue: Equation or list of equations expected instead of 0.5` in the first argument

comment Alternative to tables for textual data in Mathematica?
I have examined this on a windows 7 and 8 installation and I don't see the described phenomena. Editing the table is fluid. You could try reinstalling Mathematica, but if that fails I'd suggest contacting support@wolfram.com

@kuba and I saw you later comment too late. Too bad...

comment Package Function Confusion
@Kuba If you call the function from a Global context that wouldn't be necessary. Using $CellContext for a package sounds like a bad idea, but I don't have much experience with that, so I can't really tell.

comment Package Function Confusion
It's your use of an undefined x and y while in the Private part of the context of your package. It's rather bad practice to use and return those. If you want to return symbols from a global context I guess it would be better to introduce those as parameters to functions that you call from this package. So, function template should look like SolidShapeFunction2d[Coords_List,x_,y_]
