Looping through a list

I have a list containing maps that I want to loop through.

[
  %{book_type: "Fiction", total: 5},
  %{book_type: "History", total: 45},
  %{book_type: "Romance", total: 90},
  %{book_type: "Drama", total: 7}
]

i want to loop on this html tds

          <tr>
             <td class="text-left border-top" style="font-weight: normal !important;">books</td>
             <td class="border-top"style="font-weight: normal !important;">Fiction</td>
             <td class="border-top"style="font-weight: normal !important;">History</td>
             <td class="border-top"style="font-weight: normal !important;">Romance</td>
             <td class="border-top"style="font-weight: normal !important;">Drama</td>
          <tr>
          <td style="font-weight: normal !important;">Total</td>
           <%= for book <-@books do %>
             <td style="font-weight: normal !important;"><%= book.total %></td>
             <td style="font-weight: normal !important;"><%= book.total %></td>
             <td style="font-weight: normal !important;"><%= book.total %></td>
             <td style="font-weight: normal !important;">0<%= book.total %></td>
             <% end %>
          </tr>

I want to produce something like this

books Fiction History Romance Drama
Total 5 45 90 7

how do I go about it?

Your question isn’t very clear, but I think your desired output is the table with corresponding book_types to totals. Maybe using two loops, like this:

<tr>
  <td style="font-weight: normal !important;">Books</td>
   <%= for book <- @books do %>
     <td style="font-weight: normal !important;"><%= book.book_type %></td>
   <% end %>
</tr>
<tr>
  <td style="font-weight: normal !important;">Total</td>
   <%= for book <- @books do %>
     <td style="font-weight: normal !important;"><%= book.total %></td>
   <% end %>
</tr>

will achieve that.
