As I construct a table dynamically using JS, I encounter an issue where clicking on the btn_dropdown0 button causes it to shift slightly to the left and right. This anomaly occurs because the two empty th elements are resizing when the tbody is toggled to be visible or hidden. These blank cells seem to stretch whenever the row below them contains data.
This is my replicated table along with the jQuery code to handle the effects:
$('#btn_dropdown0').click(function() {
if($(this).css('transform') == 'matrix(-1, 0, 0, -1, 0, 0)'){
$(this).css({'transform': ''});
$('#tbody0').hide();
}else{
$(this).css({'transform': 'rotate(180deg)'});
$('#tbody0').show();
}
