title: Javascript: how to create a multi-dimensional array? (Code example needed)
body: <p>I have a table 10 rows, 10 columns. I want to define an array where I can place a value at e.g. pos. row 5, column 3. </p>
  
  <p>The value itself is an array with more entries. And the entry of this array is also an array.</p>
  
  <p>Example:</p>
  
  <pre><code>Row 1, column 1:
     My text 1, Link to text 1
     My text 2, Link to text 2
  
  Row 4, column 5:
     My text 3, Link to text 3
  
  Row 6, column 2:
     My text 1, Link to text 1
     My text 2, Link to text 2
     My text 3, Link to text 3
     My text 4, Link to text 4
  </code></pre>
  
  <p>Not every table entry needs to be defined. A table element entry can have multiple entries. An entry consists of two values. A text and the link for the text.</p>
  
  <p>The html-table is already defined. Now I want to fill it with the values (links) above.</p>
  
  <p>My problem is, how to create an efficient data structure so that I easily can find table-positions that have entries (maybe without looping 10 rows 10 columns). For each entry I want to get the list of texts + links.</p>
  
  <p>And how to access/read each entry of my definition. (I have no problem placing the value to my html-table.)</p>
  
  <p>I'd really appreciate if someone could give me some code-example how to set up such a data structure.</p>
