Data table question (manipulation)

Hey Automation Masters!

Can anyone help me with my data table question?

I have two data tables with different columns both DT except of one of the columns. I am trying to compare one DT against the other and if the values match then update a column with a new value. Does anyone know how to do this? I am new to uipath so would love your help!
