Key Fixes & Improvements:
Ensure Row Completion: The <tr> element inside renderHabits() seems cut off. Ensure it is properly closed.
Allow Habit Tracking Per Day: You're tracking habits per day, but it's not visible in the current setup. We need to make each cell clickable to toggle completion.
Update renderHabits() to Display Days Correctly: Right now, it looks like habits are stored with habit.dates[dateKey], so we need to reflect that in the UI.
Fixed renderHabits() Function
This version properly updates the habit tracker grid.

js
Copy
function renderHabits() {
  const tbody = document.getElementById('habitTableBody');
  tbody.innerHTML = '';

  if (habits.length === 0) {
    const emptyRow = document.createElement('tr');
    const daysInMonth = new Date(currentDate.getFullYear(), currentDate.getMonth() + 1, 0).getDate();
    emptyRow.innerHTML = `
      <td class="habits-column">No habits yet</td>
      ${Array(daysInMonth).fill('<td></td>').join('')}
      <td class="goal-column">-</td>
    `;
    tbody.appendChild(emptyRow);
    return;
  }

  habits.forEach((habit) => {
    const row = document.createElement('tr');
    row.innerHTML = `<td class="habits-column">${habit.name}</td>`;

    const daysInMonth = new Date(currentDate.getFullYear(), currentDate.getMonth() + 1, 0).getDate();
    let completedDays = 0;

    for (let i = 1; i <= daysInMonth; i++) {
      const dateKey = `${currentDate.getFullYear()}-${(currentDate.getMonth() + 1).toString().padStart(2, '0')}-${i.toString().padStart(2, '0')}`;
      const isCompleted = habit.dates[dateKey];

      const cell = document.createElement('td');
      cell.classList.add('habit-cell');
      cell.dataset.habitId = habit.id;
      cell.dataset.day = i;

      if (isCompleted) {
        cell.classList.add('completed');
        cell.innerHTML = '✔️';
        completedDays++;
      } else {
        cell.innerHTML = '❌';
      }

      cell.onclick = function () {
        toggleHabitCompletion(habit.id, i);
      };

      row.appendChild(cell);
    }

    // Display habit goal progress
    row.innerHTML += `<td class="goal-column">${completedDays}/${habit.goal}</td>`;

    tbody.appendChild(row);
  });
}
CSS Fixes for UI
Make sure you have some styling to make the habit tracker look good.

css
Copy
.habit-cell {
  text-align: center;
  cursor: pointer;
  transition: background 0.3s;
}

.habit-cell.completed {
  background-color: #4CAF50;
  color: white;
}

.habit-cell:hover {
  background-color: #ddd;
}
