Using the iris data, we make a table with the `tables` package:

```
library(tables)
table <- tabular( (Sepal.Length+Sepal.Width) ~
           Format(format(digits=2))*(mean + sd), data=iris )

```

With the `Hmisc` package, we would add the caption with the `latex` function like this:

```
latex(table, caption="My table")

```

But that does not work with the `tables` package, because it defines an S3 method, `latex.tabular`.

So I have tried this, following an example in the [package vignette](http://cran.r-project.org/web/packages/tables/tables.pdf):

```
latex(table, options=list(toprule="\\caption{My table}"))

```

But it does not work, it says that caption is outside float. How can I correctly add caption with the `latex.tabular` function from the `tables` package?
