jquery - Removing extra padding in DataTables columns -


hi have created jquery datatables looks this:

enter image description here

so question how remove padding in "picture" column?

this how initialize table:

$('#violators_tbl').datatable({             "aocolumndefs": [                 { "bsortable": false, "atargets": [ 2,3 ] },                 { "swidth": "20%", "atargets": [ 0 ] },                 { "swidth": "35%", "atargets": [ 1 ] },                 { "swidth": "30%", "atargets": [ 2 ] },                 { "swidth": "15%", "atargets": [ 3 ] },             ],         }); 

this how add rows table:

function update_table(violator){         var img_str1 = '<img class=\"obj-pic\" src=\"' + main.vars.base_path + violator.front_temp_file_path + '\">';         var img_str2 = '<img style=\"margin-left: 10px;\" class=\"obj-pic\" src=\"' + main.vars.base_path + violator.rear_temp_file_path + '\">';         var img_str3 = '<img style=\"margin-left: 10px;\" class=\"obj-pic\" src=\"' + main.vars.base_path + violator.right_temp_file_path + '\">';         var img_str4 = '<img style=\"margin-left: 10px;\" class=\"obj-pic\" src=\"' + main.vars.base_path + violator.left_temp_file_path + '\">';         violators_table.datatable().fnadddata([             violator.violator_id,             violator.get_full_name(),             'under construction',             img_str1 + img_str2 + img_str3 + img_str4,         ]);     } 

easier way add sclass option adds class designated columns. thereafter, can style my_class according needs. way, specific table instance affected , not others in application.

$('#violators_tbl').datatable({     "aocolumndefs": [       { "sclass": "my_class", "atargets": [ 0 ] }     ]   } );
