I. Overview
1.1 Problem description
By default, when the report is previewed, the column width cannot be freely modified. In some requirements, the column width should be changeable to achieve the effect as shown in the figure below. How to achieve this demand?
Note: If there are merged cells, you can only drag the cells in the first row to adjust the column width.
1.2 Implementation ideas
We need to use third-party codes, and you can refer to: http://www.bacubacu.com/colresizable/.
Note: The example in this document uses third-party codes, so it is only for reference. If it no longer takes effects, you can refer to the website of the third-pary code for modification.
II. Example
2.1 Operation steps
Click Template > Web Attributes, choose to Individually set for the template, and add a Loading End event.
The JS codes:

e,i=t(document),r=t("head"),o=null,s={},d=0,n="id",a="px",l="JColResizer",c="JCLRFlex",f=parseInt,h=Math,p=navigator.userAgent.indexOf("Trident/4.0")>0;try{e=sessionStorage}catch(g){}r.append("<style

$(function(){
$(".x-table").colResizable(); //load colResizable method
});
The first line is the third-party code, and the latter is to let the table in the report to call this method.
2.2 Preview effect
After saving, click Data Entry Preview, and the effect is as shown in the figure below:
Note: The mobile terminal and H5 do not support this effect.
