select row with single selection, zeroed out columns to right of selection

[datasmithtech]

i was using template for each cell, and also <div based on evaluating condition using ngif

when i selected a row, contents to right of selected column were cleared

didn't occur for any subsequent row selection

i found as i stepped out of event handler, that when the row was highlighted as i stepped out from event handler, then the row contents got cleared by datatable code.
