Difficulty in getting a table to format correctly Options

[Dave R]

Dear All

I am attempting to complete a past paper question with my students. The question asks for a table 1200px wide,
the first row is made up of 3 x 400 x 300 cells
the second row is 1 x 1200 x 250 cell
the third row is 1 x 1200 x 150 cell
the fourth row is 2 x 600 x 300 cells.

Up to the final row, the table appears as expected - the fact the final row effectively divides the row in the centre means we would need to use a colspan in the first row so the middle cell is colspan=2. However, as soon as the final row goes in, the first and last row get distorted, and I can't get the two cells in the bottom row to balance correctly. Here's my code:

CODE

<table style = "border:4px solid black; border-collapse:collapse;">
            <tr style = "height:300px;">
                <td style = "border:2px solid black; width:400px;">A</td>
                <td colspan = 2 style = "border:2px solid black; width:400px;">B</td><!--colspan to allow the bottom row the chance to divide this cell -->
                <td style = "border:2px solid black; width:400px;">C</td>
            </tr>
            <tr style = "height:250px;">
                <td colspan = 4 style = "border:2px solid black; width:1200px;">D</td>
            </tr>
            <tr style = "height:150px;">
                <td colspan = 4 style = "border:2px solid black; width:1200px;">E</td>
            </tr>
            <tr style = "height:300px;">
                <td colspan=2 style = "border:2px solid black; width:600px;">F</td>
                <td colspan=2 style = "border:2px solid black; width:600px;">G</td>
            </tr>
        </table>

Any suggestions on how to get it to appear correctly would be very much appreciated. Thanks in anticipation,

Dave

Indeed it does! Thanks Pandy.

I am not sure why that should be necessary, as the total width of each row is 1200px anyway, but your suggestion provides a working solution.

Me neither. I tested in several other browsers, only chromium misbehaved.
