.interactive dataframe repr: table columns overlap

### ALL software version info
```
hvplot : 0.8.0
pandas : 1.4.3
holoviews : 1.14.9
bokeh : 2.4.3

Python version : 3.9.13
IPython version : 8.4.0
jupyter notebook : 6.4.12
jupyterlab : 3.4.3

OS : Darwin ( = MacOS 11.5.2)
Release : 20.6.0
Browser : Safari
```

### Description of expected behavior and the observed behavior
The columns of the dataframe representation in both jupyter notebook and jupyter lab are too narrow, so numbers overlap for a particular example dataframe.

### Complete, minimal, self-contained example code that reproduces the issue

```
import hvplot.pandas
from bokeh.sampledata import airports

df = airports.data
df1 = df.interactive()
df1 # show dataframe
```

Performing a dynamic calculation on the dataframe doesn't change that behavior
```
p = pnw.IntSlider(start=0, end=100)
df1[df1.index

### Expected behavior
