how do i write xpath of an element inside iframe

Question

I am trying to click on an element present inside iframe, the xpath which i have written is showing as 1 of 1 during testing, but is not highlighting anywhere until i click on the report manually. 

element location details: //div[@row=1 and @column=6 and @class='sf-element-table-cell flex-justify-center flex-align-start  sfc-value-cell sfpc-value-cell']

iframe details: //iframe[@id='Measurereport']

is there a way to get the xpath of the element by merging the iframe and element xpath. I couldn't find a valid xpath when tried to merge them using /following-sibling::
