How do I email an update to the table results for specific columns that meet the criteria less than 0? - google-apps-script

Question

I have a table that I would like to send an email for based on the values of columns E(table below). The Columns I would like to append to the email are A,D,E,F. The Rows I would like to include are those that have dropped below 0 from column E. How do I amend my function to allow for this change?
function EmailUpdate() {
var hty = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Historical')
var data = hty.getRange("A1:F" + hty.getLastRow()).getValues().filter(([,e], i) => i == 0 || e < 0);
var TABLEFORMAT = 'cellspacing="2" cellpadding="2" dir="ltr" border="1" style="width:100%;table-layout:fixed;font-size:10pt;font-family:arial,sans,sans-serif;border-collapse:collapse;border:1px solid #ccc;font-weight:normal;color:black;background-color:white;text-align:left;text-decoration:none;font-style:normal;'
var htmltable = '<table ' + TABLEFORMAT + ' ">';
for (row = 0; row < data.length; row++) {
htmltable += '<tr>';
for (col = 0; col < data[row].length; col++) {
if (data[row][col] === "" || 0) {
htmltable += '<td>' + 'None' + '</td>';
} else
if (row === 0) {
htmltable += '<th>' + data[row][col] + '</th>';
} else {
htmltable += '<td>' + data[row][col] + '</td>';
}
}
htmltable += '</tr>';
}
htmltable += '</table>';
Logger.log(data);
Logger.log(htmltable);
MailApp.sendEmail(Session.getActiveUser().getEmail(), 'Email Report', '' ,{
htmlBody: htmltable
})
}

Replace:
var data = hty.getRange("A1:F" + hty.getLastRow()).getValues().filter(([,e], i) => i == 0 || e < 0);
With:
var data = hty.getRange("A1:F"+hty.getLastRow()).
getDisplayValues().
map(([a,,,d,e,f]) => [a,d,e,f]).
filter((r,i)=>r[2].includes("-") || i==0 );
