I want add a key up event to every text box element in a table excluding the last text box in each row. The table is dynamic on both axis.

The key up event will total the values in all but the last text box. The total is then placed in the last text box for the row. 

The script for the totaling and setting the total all works fine. 

I tired the following to select the target elements:

```
$("#Grid tr input:text:not(:last)").keyup(function(){
    //do total stuff here
})

```

Unfortunately it works as documented and not as I wanted and selects all but the very last checkbox.

Ideally the solution will not involve any further markup to the table example below or involve any looping. However if that is what it takes, so be it. 

```
<table id="Grid">
    <tr id="r1">
        <td>Row 1</td>
        <td><input type="text" id="txt_a1_b1"></td>
        <td><input type="text" id="txt_a1_b2"></td>
        <td><input type="text" id="txt_a1_b3"></td>
        <td><input type="text" id="txt_a1_b4"></td>
        <td><input type="text" id="total_a1"></td>
    </tr>
    <tr id="r2">
        <td>Row 2</td>
        <td><input type="text" id="txt_a2_b1"></td>
        <td><input type="text" id="txt_a2_b2"></td>
        <td><input type="text" id="txt_a2_b3"></td>
        <td><input type="text" id="txt_a2_b4"></td>
        <td><input type="text" id="total_a2"></td>
    </tr>
    <tr id="r3">
        <td>Row 3</td>
        <td><input type="text" id="txt_a3_b1"></td>
        <td><input type="text" id="txt_a3_b2"></td>
        <td><input type="text" id="txt_a3_b3"></td>
        <td><input type="text" id="txt_a3_b4"></td>
        <td><input type="text" id="total_a3"></td>
    </tr>
</table>

```

One final point, the total text box does need to be a text box as there is also a requirement to enter a total then split it across the row and I do not want a key up function in the total text box.
