Hi,

suppose I have a heavily scaled 2D histogram with underflow and overflow. I want to show this underflow and overflow table in the `TPaveStats`

. This table is shown in terms of the integral, so when these numbers are very small, I see only “0” instead of “0.0001” or the like. How do I change the format of the numbers in that table?

The following code serves as a minimal reproducer:

```
gStyle->SetOptStat("eiuo");
TH2F* myH = new TH2F("myH", "My histogram;X;Y;Z", 10, 0., 10., 10, 0., 10.);
myH->Fill(5., 5., 1.);
myH->Fill(-5., -5., 1.); // underflow!!
myH->Scale(1e-3);
myH->Draw("colz");
```

and I get this:

So I’m interested in a way to change the content of this table (encircled in red) to something like this:

```
-----------------------
| 0 | 0 | 0 |
-----------------------
| 0 | 0.001 | 0 |
-----------------------
| 0.001 | 0 | 0 |
-----------------------
```

or maybe

```
---------------------
| 0 | 0 | 0 |
---------------------
| 0 | 1.e-3 | 0 |
---------------------
| 1.e-3 | 0 | 0 |
---------------------
```
