Grid gets small when a user changes column width

I’m getting issues when a user resizes one column, the whole grid began to shrink and the column width still the same
I’m using bootstrap 3.3.7 and here is my code


<div id="gridbox" style="width: 100%;height: 450px;"></div>

mygrid = new dhtmlXGridObject('gridbox');	
      mygrid.setImagePath(".../dhtmlxSuitePro/dhtmlxGrid/codebase/imgs/");
      mygrid.setHeader("X,X,X,X,X,#cspan,X,X,X,X,X,X");   mygrid.attachHeader("#text_filter,#text_filter,#text_filter,#text_filter,,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter");
      mygrid.setInitWidths("*,*,*,80,40,*,*,*,*,*,*,90");
      mygrid.setColAlign("left,left,left,left,center,left,left,left,left,left,left,left");
      mygrid.setColTypes("ro,ro,ro,ro,ro,ro,ro,ro,ro,ro,ro,ro");
      mygrid.setColSorting("str,str,str,str,str,str,str,str,str,str,str,str");
      mygrid.enableMultiline(true);	
     mygrid.setSkin("material");
      mygrid.init();
 mygrid.parse(js,"json");

The initial size

After trying to adjust column width with the mouse

Your bootstrap css redefines the sizes of the html table.
Please, check if you’ve defined the sizes of your html body. Also check your custom css.

i have the same problem.

Did you try the suggestion?:
