@misc{hepdata.42740, author = "{D0 Collaboration}", title = "{Measurement of the ratio of the $p \bar{p} \to W^+ c^-$ jet cross section to the inclusive $p \bar{p} \to W +$ jets cross section}", howpublished = "{HEPData (collection)}", year = 2008, note = "\url{https://doi.org/10.17182/hepdata.42740}" }

or, if you prefer, a specific version of the record:

@misc{hepdata.42740.v1, author = "{D0 Collaboration}", title = "{Measurement of the ratio of the $p \bar{p} \to W^+ c^-$ jet cross section to the inclusive $p \bar{p} \to W +$ jets cross section (Version 1)}", howpublished = "{HEPData (collection)}", year = 2008, note = "\url{https://doi.org/10.17182/hepdata.42740.v1}" }

You can also cite this table directly.

@misc{hepdata.42740.v1/t2, author = "{D0 Collaboration}", title = "{``Table 2'' of ``Measurement of the ratio of the $p \bar{p} \to W^+ c^-$ jet cross section to the inclusive $p \bar{p} \to W +$ jets cross section'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2008, note = "\url{https://doi.org/10.17182/hepdata.42740.v1/t2}" }
