If Callback_column used to call such a function and change color fields to export when you leave the tags in HTML


$value="<b><font color='#666600'>".$value."</font></b>";
$value=trim($value);



Fco. Orellana Maquinaria No 1 (Babor) <b><font color='orange'>23731</font></b>
Fco. Orellana Maquinaria No 3 (Estribor) <b><font color='orange'>23735</font></b>

Is solved by going to the grocery crud Liberia, and adding

libraries\grocery_crud.php


foreach($data->list as $num_row => $row){
foreach($data->columns as $column){
//$string_to_export .= $this->_trim_export_string($row->{$column->field_name})."\t";
$string_to_export .= strip_tags($this->_trim_export_string($row->{$column->field_name})."\t");
}
$string_to_export .= "\n";
}
