React Map Method within Map Method

I am trying to include map method in a map method while getting a list as an element from the first map method.

      {columns &&
        columns.map(column => 
        column.list && column.list?
        (column.list.map((item)=>{
        return (
        <CustomTableCell align="center">{item.name}
        <span>{item.convertMethod(item.id, item.lists)}</span>
        </CustomTableCell>
         );
         })):            
        <CustomTableCell align="center"> {column.name} </CustomTableCell>                                        
           ) }

Error still exists
