Use addStyle:
uit = uitable(...);
s = uistyle('BackgroundColor','red');
addStyle(uit,s,'column',2)

Update:
f = uifigure;
uit = uitable(f, Data = "hi");
s = uistyle('BackgroundColor','red');
addStyle(uit,s,'column',1)
Original Answer
Hi,
this is pretty tricky within an uitable since the text you display will have a red background and not the full cell in the table:
uitable('Data',{'<body bgcolor="#FF0000">Hello</body>'})
You will see that Hello has a read background but thats all.
So we can do a small trick. Instead of adding the text we add a html table which contains the text. In addition this html table is sooooo wide that it needs the full cell^^:
uitable('Data',{'<table border=0 width=400 bgcolor=#FF0000><TR><TD>Hello</TD></TR> </table>' })
So overall you can do a colored table like this:
colergen = @(color,text) ['<table border=0 width=400 bgcolor=',color,'><TR><TD>',text,'</TD></TR> </table>'];
data = { 2.7183 , colergen('#FF0000','Red')
'dummy text' , colergen('#00FF00','Green')
3.1416 , colergen('#0000FF','Blue')
}
uitable('data',data)

This is such an improvement on the more common method of just giving a font a bgcolor. Thanks Friedrich!

Brilliant. I can't explain how much you've just helped me! The uitable still allows for resizable columns, and the background goes with it.

This answer does not work for me in MATLAB 2018b. It is just showing a table with the html as text.

In the colergen function, use '<html><table' instead of just '<table'

It's not working, any idia why?

Works for me when I try. Which MATLAB release are you using?

I get the same results- html is not interpreted. It works when I use figure instead of uifigure:
table1 = uitable(figure);
table2 = uitable(uifigure);
When I do the above changes to table1 - the html is interpreted and I get colored cells, but not for table2. I am using Matlab 2018b

uifigure have a different underlying technology that does not support HTML like this. I have not researched them to see what is possible.

I have this example working only after adding an '<html>' tag to the above:
colergen = @(color,text) ['<html><table border=0 width=400 bgcolor=',color,'><TR><TD>',text,'</TD></TR> </table>'];

I need to change the color of each row in uitable(uifigure). If I'm using the html code, it is not interpreting the html as pointed out by Rafael and Simeon Georgiev. Can anyone suggest me how to tackle this issue?? I need a workaround for it.

For uitable that are inside uifigure, before R2019b there was only hacks.
As of R2019b, uitable inside uifigure can have styles configure for them. See https://www.mathworks.com/help/matlab/ref/matlab.ui.control.tableappd.addstyle.html

Thanks. Yeah, I read about it too. But the problem is, I'm currently on 2019a and I need the code to work with 2016 version onwards. So, I'm much more interested in the hacks. Could you please share?

Eric Sargent, it would appear that uistyle, addStyle, and removeStyle functions only work on uitable when the uitable is made in a uifigure, but not when a uitable is made in figure. That has me stuck at the moment.
Error using matlab.ui.control.Table/addStyle (line 63)
Functionality not supported with figures created with the figure function.

In Matlab 2017a (and at least as far back as 2013b) this has improved. The uitable now has a "BackgroundColor" property. This is an array of n rows and 3 columns, RGB values between 0 and 1. It appears that if this array has less rows than the data in the table, then the colours are repeated throughout the table.
To highlight a single row, create a colour array the same size as your data and specify the row of interest as the colour you want.
This is how the alternating row colours are created (and so those colours can be changed if you want as well).

Hello, that is my way to try to get the GUI uitable BAckgroundColor changed. But it is only changing the whole uitable. I want it to just change the row of the checkbox green if the checkbox is 1 and if checkbox is 0, change to red background of the row. Thanks for your help. best regards

You could try
'<HTML><TD BGCOLOR=#40FF68>Hello</TD>'
