# Use the booktabs option to improve presentation of the table.
ds %>% kable(row.names=FALSE, digits=0, booktabs=TRUE)| Location | MinTemp | MaxTemp | Rainfall | Evaporation |
|---|---|---|---|---|
| Sydney | 13 | 30 | 0 | 6 |

| MountGinini | -4 | -1 | 5 | NA |
| Williamtown | 7 | 18 | NA | NA |
| Penrith | 12 | 18 | 0 | NA |
