Troubleshooting HTML Code to Show 'No Data' in Pop-Up Table without Empty Cells

I was given a layer with overlapping polygons and tasked with dividing it into 4 square km cells. My goal is to create a pop-up table that displays different species in each cell. To achieve this, I need to write HTML code that checks if there are any species present in a cell and displays them, or displays "no data" if there are none.

To accomplish this, I created 26 Arcade expressions, with the last two expressions handling the "no data" cases. However, I encountered an issue where clicking on a cell that should display "no data" also displayed empty cells for other expressions. I want to modify the HTML code to prevent the display of these empty cells.

I'm uncertain if HTML can include an if statement. How I can get rid of these empty rows?

var species1 = $feature.species1;
var species2 = $feature.species2;
var species3 = $feature.species3;
var species4 = $feature.species4;

if (species1 || species2 || species3 || species4) {
  return Concatenate(If(species1, 'Species 1<br>', ''), If(species2, 'Species 2<br>', ''), If(species3, 'Species 3<br>', ''), If(species4, 'Species 4<br>', ''));
} else {
  return 'No data';
