Hi guys,
This time this is my new question. Is there a way I can manually select a column, for example by clicking a button?
Detailed example: I have a button called “Select column 3”, when the user clicks the button, it should manually select column 3 and give it a custom background color as well coz I’m planning to change the default background.
Is that possible?
Hi @hugh
yes, there is. We have 3 related methods
Here are all those methods in use https://jsfiddle.net/9ceoyqga/
If you’d like to select a whole row you can use selectCell() and countCols() method, like here https://jsfiddle.net/9ceoyqga/1/
Thanks for that detailed demos. By the way, is there a way I could also change the default background color for the selected column?
Thank you.
Yes, you can. I suggest using custom classes.

ps. here’s a list of supported className changes
you’re welcome 
Hi again @aleksandra_budnik ,
Ahm I hope it’s alright if I will add a follow-up question coz it’s somehow related. What if I add a custom background without selecting the column/s.
For example, what if I just want to permanently set background color for columns 1 and 3 to be green. You know, just to set these columns noticeable - to let the user know that these columns are quite important than the other columns. I’ve read about setCellMeta, but I don’t know how to use/implement it.
Thank you for taking the time.
@hugh here’s an example https://jsfiddle.net/Lgtumo12/
I’m using cells method to handle classes for cells and afterGetColHeader hook to attach classes to headers.
I always happy to help
