我正在尝试使用jAutoCalc插件对数字进行一些计算 没关系，计算正确。
但是当我尝试使用jquery.repeater插件向表中添加行时， 新行不计算在内。 另外，当我删除行表格时，总金额未更新！
有什么帮助吗？

在表中进行任何修改后，您应该调用 autoCalcSetup（）函数。
示例： https://jsfiddle.net/214umqL6/
/** autoCalc **/
$(document).ready(function() {
function autoCalcSetup() {
$('table').jAutoCalc('destroy');
$('table tr').jAutoCalc({
keyEventsFire: true,
decimalPlaces: 2,
emptyAsZero: true
});
$('table').jAutoCalc({
decimalPlaces: 2
});
}
autoCalcSetup();
/** confirm delete row **/
$('#deleteRow').on('shown.bs.modal', function(e) {
// store the clicked element as data on the confirm button
$('#confirmDeleteBtn').data('triggered-from', e.relatedTarget);
});
$('#confirmDeleteBtn').click(function() {
// retrieve the button that triggered the action and use it
var trigger = $(this).data('triggered-from');
autoCalcSetup(); // call the function
$(trigger).closest('tr').remove();
$('#deleteRow').modal('hide');
});
});<div class="repeater">
<table class="table table-striped table-bordered table-hover mb-0" data-repeater-list="category-group">
