Picking | as the delim makes it look more like a table in the source, and you don't have to worry about aligning everything (the spaces before and after the delim are ignored by default). But it does require some boilerplate and you can't wrap the lines. The same table as an example: .. csv-table:: Block Structure :delim: | :header-rows: 1 :widths: auto Offset | Type | Name | Description 0x0 | Array of __le32 entries | Orphan inode entries | Each __le32 entry is either empty (0) or it contains inode number of an orphan inode. blocksize-8 | __le32 | ob_magic | Magic value stored in orphan block tail (0x0b10ca04) blocksize-4 | __le32 | ob_checksum | Checksum of the orphan block. Obviously not the best choice for this particular table, but just so you are aware of an alternative. BR, Jani.
