I have a tool which plots data based on the user selection. The tool plots the line on 3 graphs and I've created uitable which displays the properties of the plotted line. I want to update the color of the text of the row according to the color of the line plotted. The table should get updated whenever a new line is plotted as well as the color of that one row only should change. How can I do that?
function tab_input(ui_table,cell_1a,cell_1b,cell_2,cell_3)
cell_1 = strcat(cell_1a,cell_1b,cell_1a);
existingData = get(ui_table,'Data');
tempData = {cell_1,cell_2,cell_3};
newData = [existingData;tempData];
set(ui_table,'Data',newData,'ForegroundColor',ci_color(cell_2));
end
In the above code, I want to append the table as well as, I want to change the textcolor of the current row only, whereas the color or the previous row (if any) should remain unaltered. Please suggest a workaround.

I've found a workaround for this problem. Instead of changing the foreground, I'm changing the background. The background color of each row is saved in a matrix containing the RGB values of each row of the table. This matrix is passed as a 'BackgroundColor' argument while displaying the uitable.

I checked it and tried at my end. When I enter the following code:
uitable('Data',{'<html><body text color="#FF0000">Hello</body></html>'});
We get a table with a cell in which 'Hello' is written in red color.
I already have a uifigure open and a uitable has been built as its child. When I try to enter the data in this table as:
uitable(fig,'Data',{'<html><body text color="#FF0000">Hello</body></html>'});
It does not recognise the html code but gives this as output:
What could be the issue?

As an alternative, is it possible to change the background color of each row? It should work like whenever I add a new row, the background color of that row should change as per the value of decision variable (cell_2 in this case).
