Correct thead and tbody for a table structure?

Hello, until recently I have always written a html table like this:

Table Example 1a

HTML Code:

---

<table summary="an example of writing a table">
  <tr>
      <th scope="col">Table Header 1</th>
      <th scope="col">Table Header 2</th>
      <th scope="col">Table Header 3</th>
  </tr>
  <tr>
      <td>Table Data 1</td>
      <td>Table Data 1</td>
      <td>Table Data 1</td>
  </tr>
<table>

---

Table Example 2a

HTML Code:

---

<table summary="an example of writing a table">
  <tr>

      <th scope="row">Table Header 1</th>
      <td>Table Data 1</td>

      <th scope="row">Table Header 2</th>
      <td>Table Data 1</td>

      <th scope="row">Table Header 3</th>
      <td>Table Data 1</td>

  </tr>
<table>

---

But I while creating a JavaScript program, I have descovered that if I want to dynamically add a table in IE then the table needs a tbody or IE JavaScript refuses to add the table dynamically, so I am now trying to think how to use thead and tbody correctly.

For example 1a it seems pretty easy:

Table Example 1b

HTML Code:

---

<table summary="an example of writing a table">
  <thead>
      <tr>
        <th scope="col">Table Header 1</th>
        <th scope="col">Table Header 2</th>
        <th scope="col">Table Header 3</th>
      </tr>
  </thead>
  <tbody>
      <tr>
        <td>Table Data 1</td>
        <td>Table Data 1</td>
        <td>Table Data 1</td>
      </tr>
  </tbody>
<table>

---

But I dont know how you would do Table Example 2a ?

Table Example 2b

HTML Code:

Thanks

Code HTML4Strict:

---

<table summary="an example of writing a table">
  <tbody>
     <tr>
 
        <th scope="row">Table Header 1</th>
        <td>Table Data 1</td>
 
        <th scope="row">Table Header 2</th>
        <td>Table Data 1</td>
 
        <th scope="row">Table Header 3</th>
        <td>Table Data 1</td>
 
     </tr>
  </tbody>
<table>

In this case you don't have a table header, so there'll be no <thead> tag.

(I must say example 2b looks odd. Should'nt it be like this?)

Code HTML4Strict:

---

<table summary="an example of writing a table">
  <tbody>
     <tr>
        <th scope="row">Table Header 1</th>
        <td>Table Data 1</td>
     </tr>
 
     <tr>
        <th scope="row">Table Header 2</th>
        <td>Table Data 2</td>
     </tr>
 
     <tr>
        <th scope="row">Table Header 3</th>
        <td>Table Data 3</td>
     </tr>
  </tbody>
<table>
