How to hide extjs grid column separator? -

i hide last column separator extjs grid.

is there way it?

you can add flex:1 last column in grid stretch remaining distance left in grid then.

here's simple example:

ext.define('app.view.examplegrid', {     extend: 'ext.grid.panel',     xtype: 'examplegrid',     store: mystore,     columns: [             { header: 'field 1', dataindex: 'field1' },             { header: 'field 2', dataindex: 'field2' ,flex:1},     ] }); 

edit 1:

to remove line can override style border-width, create custom css file , add following (be sure include stylesheet in index.html):

.removeline {     border-width:0px !important; } 

then, set cls property of last column:

columns: [{         header: 'column out override',         dataindex: 'column1'     },  {         header: 'column override',         dataindex: 'column2',         cls:'removeline'     }]
