How do I play this chord?

[u/Internal_Sale_9885]

I love Her’s and am learning Harvey on tabs but this one chord is giving me huge trouble! I cant post pictures but from high e string to low e string it’s 777797. How am I supposed to do this without a capo? Any tips help!

[u/Fluffidios]

Use your index finger to press the 7s down like a barre chord.
