How can I merge cells with the same data?

# What I want
I want to merge cells with same data in a specific row as below. ( Please ignore the "No" column. )

## Current Behavior
I configured the column like this:
( Because it is in the middle of migration from tui-grid, there may be some unnecessary options. please ignore them)
```js
const columns = [
{
name: 'analyst', label: 'ANALYST',
options: {
width: 'auto',
minWidth: 100,
rowSpan: true,
sort: true,
}
},
]
```


I configured MUIDataTable like this:

```

```
And this renders the table like below.


I've read the documentation and search to get the results I want, but couldn't find a way.
Is there any effective way?

### My Environment

| React | 17.0.2 |
| browser | chrome |

No source files, tests, or entry points are named in the issue. Start by tracing how MUIDataTable renders rows and applies column options, then determine whether the requested same-value cell merging fits the existing table behavior. Done means the requested row grouping is supported and documented with verification for repeated values.
