How to format this datatables export to excel?

I have a datatable where I am exporting the results in excel spreadsheet. Most of the rows have long text along with some formatting such as line breaks, lists.

Is there a way to do the following when exporting to excel?

  1. Wrap text for all the cells
  2. Preserve line breaks, p and ul tags.

Here is my example: https://live.datatables.net/yamifera/1/edit

$(document).ready(function() {
  var table = $('#example').DataTable({
    responsive: true,
    searching: true,
    columnDefs: [{
      target: 6,
      visible: false,
      searchable: true,
    }],
    dom: 'Bfrtip',
    buttons: [{
        extend: 'excelHtml5',
        exportOptions: {
          columns: ':visible'
        }
      },
      {
        extend: 'pdfHtml5',
        orientation: 'landscape',
        exportOptions: {
          columns: ':visible'
        }
      },
      {
        extend: 'print',
        exportOptions: {
          columns: ':visible'
        }
      },
      //  'colvis'
    ],
  });

  buildSelect(table);

  table.on('draw', function() {
    buildSelect(table);
  });
  $('#test').on('click', function() {
    table.search('').columns().search('').draw();
  });
});

function buildSelect(table) {
  var counter = 0;
  table.columns([0, 1, 2]).every(function() {
    var column = table.column(this, {
      search: 'applied'
    });
    counter++;
    var select = $('<select><option value="">select me</option></select>')
      .appendTo($('#dropdown' + counter).empty())
      .on('change', function() {
        var val = $.fn.dataTable.util.escapeRegex(
          $(this).val()
        );

        column
          .search(val ? '^' + val + '$' : '', true, false)
          .draw();
      });

    column.data().unique().sort().each(function(d, j) {
      select.append('<option value="' + d + '">' + d + '</option>');
    });

    // The rebuild will clear the exisiting select, so it needs to be repopulated
    var currSearch = column.search();
    if (currSearch) {
      // ** MY CHANGE **
      // Use RegEx to find the selected value from the unique values of the column.
      // This will use the Regular Expression returned from column.search to find the first matching item in column.data().unique
      select.val(column.data().unique().toArray().find((e) => e.match(new RegExp(currSearch))));
    }
  });
}

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
