Need to Merge Two DataTable with same Columns in Powerapps

[ajyendra24]

Hi @v-xida-msft ,

I think It is because i have created two datatable name AccountDb and ContactDb . And Now What I am doing is merge these two datatable into one. But when we use AddColumns(AccountDb,"MainPhone",LookUp(--- check refernce),'Main Phone') it is not working because AccountDb datatype is now Control instead of TABLE . Same code is used directly to Account table it works like AddColumns(Accounts,"MainPhone",LookUp(---Checkreference--),'Main Phone').

Please Give suggest what I do to merge through that AccountDb Table which I created in PowerApps

Hope You understand What I am Trying to say

Thanks
