Hi @matstein, I just added "height:100% !important;" in every class. I tried it on my end and it works! <style> .cbGridCtnr > .HeadCtnr { width: 100% !important; height: 100% !important; } .cbGridCtnr > .HeadCtnr > .Table { width: 100% !important; height: 100% !important; } .cbGridCtnr > .BodyCtnr .Cell > .Data { width: 100% !important; height: 100% !important; } .cbGridCtnr > .BodyCtnr > .Table{ width: 100% !important; height: 100% !important; } </
