Not sure I understand what you mean? Do you want to colour these cells too ?
I need to add another row.
To do this, I save the first three columns of data in Firebase in a tag, highlighting the commas.
And the cells that will be colored in another tag.
Once saved in Firebase, I retrieve them and combine them to create the table.
But I need to save the content.
#r7c33, #r7c34, #r7c35, #r7c36, #r7c37, #r7c38
But I only have
#r7c33
#r7c38
I need the green one
Another detail is that I'd like to stabilize the first three columns, including the header.
How can I stabilize all three?
td:nth-child(3){background-color:green;position:sticky;left:0;}
what about td:nth-child(1), td:nth-child(2), td:nth-child(3) {....}
This only gives me the color, but it doesn't stabilize it.
td:nth-child(1),td:nth-child(2),td:nth-child(3){background-color:green;position:sticky;left:0;}
This is what I'm looking for:
- Stabilize the first 3 columns
- Join:
1 and 2 of column 1
1 and 2 of column 2
1 and 2 of column 3
just like the video
For setting column widths try like so, you may need to adjust your table width accordingly:

@Kevinkun may have a better method for this...
