The following code prints nicely the table
<?php
$lines = file('graphdata/GapsVsOthersForDimsOthersJson.csv');
foreach ($lines as $lineNum => $line) {
if($lineNum == 0) {
continue;
}
print " <tr id=\"tr" . $lineNum . "\">";
$tokens = str_getcsv($line);
/*print "<td style=\"width: 200px;\">" . trim($tokens[0]) . "</td>";*/
print "<td style=\"width: 300px;\">" . trim($tokens[0]) ."</td>";
print "<td style=\"width: 100px;\">" . trim($tokens[1]) . "</td>";
print "<td style=\"width: 100px;\">" . trim($tokens[2]) . "</td>";
print "<td style=\"width: 100px;\">" . trim($tokens[3]) . "</td>";
print "<td style=\"width: 100px;\">" . trim($tokens[4]) . "</td>";
print "<td style=\"width: 100px;\">" . trim($tokens[5]) . "</td>";
print "<td style=\"width: 100px;\">" . trim($tokens[6]) . "</td>";
print "</script>\n";
}
?>
I want to format the token(4) cell based on values of token(2) and token(3):
Red background if the value is smaller than token(2)-1.1*token(3).
Green background if the value is greater than token(2)+1.1*token(3)
Please advise

You could just set up some conditional statements. First of all, I recommend using a stylesheet instead of inline styling; it's much cleaner, so you could simply name some classes for different conditions.
for example, you could do something like this
if ($tokens[4] < ($tokens[2]-(1.1*$tokens[3])) {
echo '<td class="tokenred">' . trim($tokens[4]) . '</td>';
}
else if ($tokens[4] > ($tokens[2]+(1.1*$tokens[3])){
echo '<td class="tokengreen">' . trim($tokens[4]) . '</td>';
}
else {
echo '<td>' . trim($tokens[4]) . '</td>';
}
and then your stylesheet would have something like
.tokenred {
background-color: #FF0000;
}
.tokengreen {
background-color: #00FF00;
}
alternately you could use inline styles if you choose
