Excel查询中添加notes列及表头行尺寸保持的技术求助

Hey Ryan, let's work through your two issues one by one to get your event table working as expected!

1. Fixing the "Can't Add New Rows" Issue #

It sounds like your existing logic handles updating notes for existing rows perfectly (persisting through status refreshes), but it's missing the step to initialize the notes column when new rows are added. Here's a practical approach to fix this:

Assuming you're using vanilla JavaScript to manage the table, you'll want to modify your row-creation function to explicitly add the notes cell and hook it up to your persistence logic. For example:

// Function to add a new event row with notes support
function addNewEventRow(event) {
  const tableBody = document.querySelector('#event-table tbody');
  const newRow = document.createElement('tr');
  
  // Add your existing event data cells (status, title, etc.)
  const statusCell = document.createElement('td');
  statusCell.textContent = event.status;
  newRow.appendChild(statusCell);
  
  // Add the notes cell with an editable input
  const notesCell = document.createElement('td');
  const notesInput = document.createElement('input');
  notesInput.type = 'text';
  // Pull saved notes for this event (if any)
  notesInput.value = localStorage.getItem(`event-notes-${event.id}`) || '';
  
  // Save notes to storage as the user types
  notesInput.addEventListener('input', () => {
    localStorage.setItem(`event-notes-${event.id}`, notesInput.value);
  });
  
  notesCell.appendChild(notesInput);
  newRow.appendChild(notesCell);
  
  tableBody.appendChild(newRow);
}

The key here is ensuring every new row gets a dedicated notes cell that's connected to your existing persistence system (localStorage, backend API, etc.). If you're using a framework like React/Vue, the idea is similar—you'll need to include the notes field in your row component template and bind it to your state/storage.

2. Fixing Header Row Size Issues #

If your header row dimensions aren't sticking, it's almost always a CSS layout conflict. Try these steps:

Step 1: Force Fixed Table Layout #

By default, tables use auto layout which lets content dictate column widths. Override this to fixed layout to respect your explicit header sizes:

#event-table {
  table-layout: fixed;
  width: 100%; /* Or set a fixed pixel width if preferred */
}

Step 2: Explicitly Set Header Column Widths #

Target the <th> elements directly to set their widths. For example, if your notes column is the 3rd column:

#event-table th {
  padding: 8px 12px; /* Add padding to prevent content overflow */
  white-space: nowrap; /* Optional: Keep header text on one line */
}

#event-table th:nth-child(1) { /* Status column */
  width: 120px;
}

#event-table th:nth-child(3) { /* Notes column */
  width: 250px;
}

Step 3: Check for Overriding Styles #

Open your browser's dev tools (F12), select the header cell, and check the "Computed" tab to see if another CSS rule is overriding your width settings. Common culprits include parent container constraints, inherited width: auto styles, or max-width rules.
