I have improved the Admixture bar charts further. As per your demands, ethnicity information is now available in a table right below the bar plot, in the same order as the bar plot IDs.
Also, you can click on any of the legend color rectangles on the right to sort the bar chart and the table by that ancestral component. Similarly, click on the header row of the table to sort by a column.
I might make some minor tweaks to this one.
