Answer 1

enter image description hereWhen you import data from external source than add an extra key value in json or js-object.,let's say isExternal which has value =''slds-theme_success" and use it is cellAttributes in lightningdatable, you can use cellAttributes in each column to highlight whole row. Ex:-

Columns=[{ label: 'test', fieldName:'test' , cellAttributes:{class: { fieldName: 'isExternal' }} } ];
