I created a table with 13 columns:
and add CSS for borders:
#q36 th {
border: 1px solid black;
padding: 2px;
text-align: center;
}
#q36 td {
border: 1px solid black;
padding: 2px;
}
When the form is loaded, 13 populated columns and 1 empty column is created:
Where is the extra column coming from and how do I get rid of it?
