Hide a column in a table

Hi <br>
I have a table <br>
id name Account country<br>
1 john 1345 usa<br>
2 yves 5789 fr<br>
3 lory 6789 it<br>
4 ciamo 889 usa<br>
<br>
but sometimes when i populate the dataset all the account column is = 'NA'<br>
id name Account country<br>
10 ivan NA usa<br>
20 nic NA fr<br>
30 malo NA it<br>
40 coti NA usa<br>
<br>
how can I hide the column Account if all dataset populated for Account is = 'NA' in order to have
<br>
<br>
<br>
id name country<br>
10 ivan usa<br>
20 nic fr<br>
30 malo it<br>
40 coti usa
