How to mark/round an element of a table/tabular?

Question

I´m creating a table for simplex, and I want to create a circle around a number in a table.

How can I make this in LaTeX?

I use PSTricks, but I prefer don´t create an image and a table/tabular inside that image.

I don´t know if in PSTricks, I can create a circle anywhere in the page or only in the rectangle in \psspicture (lower left)(upper right).

Does http://tex.stackexchange.com/questions/4850/highlighting-table-cells help? — Torbjørn T., Jun 18 '13 at 06:19
Perhaps Good way to make \textcircled numbers? is what you're looking for. — Claudio Fiandrino, Jun 18 '13 at 08:04

As far as I understand, a number for you is not

3.14159265358979323846264338327950288419716939
9375105820974944592307816406286208998628034825
3421170679821480865132823066470938446095505822
3172535940812848111745028410270193852110555964
4622948954930381964428810975665933446128475648
2337867831652712019091456485669234603486104543
266482133936072602491412737245870066063,

but rather 1, 2, 3, ...

Then one of solutions is a pifont package, where circled numbers are obtained by \ding{172}--\ding{181}, \ding{182}--\ding{191}, \ding{192}--\ding{201}, and \ding{202}--\ding{211}.

If I understood correctly, it's a table for simplex algorithm, so what happens if the OP needs 13? – Claudio Fiandrino Jun 18 '13 at 06:46
@ClaudioFiandrino Hence I am waiting for a clarification, what numbers OP has in mind. And if a circle with number 13 should be the same as the one with number 1. – Przemysław Scherwentke Jun 18 '13 at 06:51
Yes, I think in numbers like 1,2,3.... or 1.23 , 1.89, 10.34 ,... or 1.234, 5,654, 15.356..... or 1+1/2 , 12+34/21,... – Mika Ike Jun 18 '13 at 07:25
@MikaIke So dingbats are useless. But pretty! What about radii for different numbers? – Przemysław Scherwentke Jun 18 '13 at 07:54
I think that the radius should be diferent in order to the extension of the number. – Mika Ike Jun 18 '13 at 11:42
