[Plugin: WP-Table Reloaded] 3 column table

hi there i have a simple 3 column table that i made . i want each column width to be 160 px .

i used the css command per the FAQS 3 times, one time for each column as such :

.wp-table-reloaded-id-2 .column-1 {
width: 160px;
}
.wp-table-reloaded-id-2 .column-2 {
width: 160px;
}
.wp-table-reloaded-id-2 .column-3{
width: 160px;
}

everything works fine when i only have the css for the first 2 columns. once i add the 3rd column , the width of each resizes back to the default who page width.

i did enter the code “bAutoWidth”: false in the custom commands of DATAtables Javascrpit feattures section , it didnt make any difference

the url for the page where this table is :
