 ## Flags to adjust the active memory footprint
 
 |           Flag            |     Usage                      |       
-|------------------------------------------------------------|
+|---------------------------|--------------------------------|
 | `--storage-granule-size`  | By increasing the granule size you'll decrease nominal memory footprint but increase memory usage during compaction. |
 | `--storage-active-memory` | Adjust the number of bytes held in memory before being rotated out. This is the easiest way to adjust Parca's memory footprint. |
 | `--storage-row-group-size`| Smaller row groups increase memory footprint but increase query speed. Increasing row group size results in lower memory usage but slower queries. |
