推荐答案

在对应用程序的体系结构进行某些更改后，我建议采用以下方法，该方法采用本机DataTables选项和API方法:

With certain changes to the architecture of your app, I would suggest the following approach that employs native DataTables options and API methods:

//initialize DataTable
const tb = $('#example').DataTable({
  //remove non-essential controls for the sake of cleaner view
  dom: 't',
  //use columns option to setup header titles
  columns: [
    {title: 'Type'},
    {
      title: 'Amount',
      //user 'render' to append Edit/Delete buttons for each entry
      render: data => `${data}<button action="delete">Delete</button><button action="edit">Edit</button>`
    }
  ]
});
//click handler for dual purpose 'Submit' button that adds new rows and submits edits
$('#submit').on('click', function() {
  //when submit button acts to append new row to the table (default)
  if($(this).attr('action') == 'addRow'){
    tb.row.add([$("#type").val(), $("#amount").val()]).draw();
  }
  //when submit button acts to submit edits
  if($(this).attr('action') == 'confirmEdit'){
    //change affected row data and re-draw the table
    tb.row($(this).attr('rowindex')).data([$("#type").val(), $("#amount").val()]).draw();
  }
  //clean up form, switch it to default state
  $('#type').val("");
  $('#amount').val("");
  $('#submit').attr('action', 'addRow');
});
//'Delete' button click handler
$('#example').on('click', 'tbody tr button[action="delete"]', function(event){
  tb.row($(event.target).closest('tr')).remove().draw();
});
//'Edit' button click handler
$('#example').on('click', 'tbody tr button[action="edit"]', function(){
  //get affected row entry
  const row = tb.row($(event.target).closest('tr'));
  //get affected row().index() and append that to 'Submit' button attributes
  //you may use global variable for that purpose if you prefer
  $('#submit').attr('rowindex', row.index());
  //switch 'Submit' button role to 'confirmEdit'
  $('#submit').attr('action', 'confirmEdit');
  //set up 'Type' and 'Amount' values according to the selected entry
  $('#type').val(row.data()[0]);
  $('#amount').val(row.data()[1]);
});

tbody tr button {
  display: block;
  float: right;
}
