I have tried everything I have been able to find here about using colspan and initializing from html. Can you take a look and see what I’m doing wrong. This is my latest effort but colspan is not working at all on my fourth row.
cm1310 is right.
enableColSpan(mode) method requires Pro version of dhtmlxGrid.
Also make sure that you have typed the method correctly.
In your message you have typed method with doubled “l”
