KeyField auto increment

[adrienduchemin]

Hi @AllenFang, Thank you first for your work, I am using react-bootstrap-table a lot in my current project and can't wait to upgrade to react-bootstrap-table2!
I was thinking about the possibility to have the KeyField attribute not required. In that case, the key will be auto incremented for each rows (like an index). I say that because there are cases where you don't use the table in a CRUD environment and don't have ids.
Another scenario (if you still want KeyField required) would be to have the possibility to give KeyField a format like KeyField="column1-column2" so a combination of columns makes the key unique.

Actually the second scenario is a duplicate of #113 so let's just talk about the first scenario.

@adrienduchemin it's sorry for lately reply, this issue already discuss before. Actually, I still insist to have the keyField, if your data doesn't contain any id, generate one by simple sequence number then feed into the table.

Regards,
Allen

@AllenFang Thanks for the amazing work you have done.
Coming to the issue, I am also in a situation where I just need to show data, not perform CRUD over it. I prefer not to perform extra iteration over data just to add an unique key to it. I deeply feel that keyField should be optional and handled inside react-bootstrap-table2 code by generating key using map > index in ./body.js.

@adrienduchemin please take a look at #688 (comment) maybe would be helpful in this case.
