Cell needs to be defined before Row
Cell needs to be defined before Row

Since Row's styles reference ${Cell} Cell needs to be defined first

Otherwise the css the gets generated is :

```
.eUqSiS :first-child {
    border-right: 2px solid #e5e5e5;
}
``` 

notice there is no class selector before :first-child and therefore this matches every first child recursively

when patched it looks like this

```
.ldwQkG .sc-bwzfXH:first-child{
    border-right:2px solid #e5e5e5;
}
```
