Send range via email with google script - google-apps-script

Question

I want to send range by email
For example:
https://docs.google.com/spreadsheets/d/1GH5r0sY_Z-15M479xG12yCUZaV0NRU8jpkWAxPNBuwU/edit?usp=sharing
I tried this:
function sendInvoiceList(){
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Invoice").getRange("A1:B10").getValues();
var message = sheet;
var email_subj = "Invoice " + Utilities.formatDate(new Date(), "GMT+1:00", "dd.MM.yyyy");
MailApp.sendEmail({
to: "user#gmail.com",
subject: email_subj,
htmlBody: "Please send us this list:<br><br><br>" + message
});
}
The system send this:
textA1,textA2,textA3,textA4,textA5,textA6,textA7,textA8,textA9,textA10
I need value in range A1:B10 but the system only A1 separated by comma I need in column format.
How do it?
Thanks for support

Answer 1

Your setting message equal to a two dimensional array you need to rethink that. I think this maybe closer to what you want. I tested it with some data of my own but don't know what you have. Share an image of your spreadsheet if you need more assistance.
function sendInvoiceList(){
var ss=SpreadsheetApp.getActive()
var sh=ss.getSheetByName("Invoice");
var rg=sh.getRange("A1:B10")
var vA=rg.getValues();
var html='<style>td,th{border:1px solid black;}</style><table>';
vA.forEach(function(r,i){
html+='<tr>';
r.forEach(function(c,j){
if(i=0) {
html+=Utilities.formatString('<th>%s</th>',c)
}else{
html+=Utilities.formatString('<td>%s</td>',c)
}
});
html+='</tr>';
});
html+='</table>';
var email_subj = "Invoice " + Utilities.formatDate(new Date(), "GMT+1:00", "dd.MM.yyyy");
MailApp.sendEmail({to: "user#gmail.com",subject: email_subj,htmlBody: "Please send us this list:<br><br><br>" + html});
//SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html), 'Display');//Just a dialog for testing the html
}
