Creating HTML table with multiple arrays using Javascript

Budget table

I'm trying to recreate this budget table (see link above). Right now, I can't figure out how to get the table to generate everything when the page loads. I'm also confused as to how to write a loop that'll get each row to show with their header along with the cell value showing as 0. I've only been able to get the array tableHeader to show. Below is what I've done so far:

window.addEventListener('load', function() {

  let tableHeader = ["Allocated", "July", "August", "September", "October", "November", "December", "January",
    "Feburary", "March", "April", "May", "June", "Expense", "Balance", "Percent Spent"
  ];

  let tableRow = ["Salaries:", "Fringe: ", "Booking: ", "Legal Fees:", "Rent:",
    "Utilities:", "Telephone:", "Postage:", "Contractual Services", "Materials & Supplies:",
    "Travel:", "Other:", "Subtotal:", "Total:"
  ];

  let arr = [0, 0, 0, 0,
    0, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0
  ];

  //Creation of HTML table
  let table = document.createElement('table');
  let tableHead = document.createElement('thead');
  let rowHead = document.createElement('tr');


  table.appendChild(tableHead);
  tableHead.appendChild(rowHead)

  for (i = 0; i < tableHeader.length; i++) {
    let cellHeader = document.createElement('th');
    cellHeader.innerHTML = tableHeader[i]
    rowHead.appendChild(cellHeader)
  }

  function createTableBody(arr, tableRow) {
    let tableBody = document.createElement('tbody');
    let bodyRow = document.createElement('tr'); // Header row for TableRow array
    for (let j = 0; j < tableRow.length; j++) {

      let th = document.createElement('th'); //column for TableRow array
      let text = document.createTextNode(tableRow[j]); //cell
      tableBody.appendChild(th);
      bodyRow.appendChild(text);
    }

    let tr = document.createElement('tr');
    for (let l = 0; l < arr.length; l++) {

      let td = document.createElement('td'); //column
      let text = document.createTextNode(arr[l]); //cell
      td.appendChild(text);
      tr.appendChild(td);
    }

    tableBody.appendChild(tr);
  }


  document.getElementById("tableDiv").appendChild(table);
  document.getElementById("tableDiv").appendChild(tableBody);


});
th {
  border: 1px solid black;
  padding: 5px;
}

table {
  border-collapse: collapse;
}

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
