While we could easily use HTML or CSS formatting to do this, this would be bad for performance in a large data table, may cause some issues when editing table cells or sorting columns.

data rows that have statistical significance (%p-value < 5) should have a yellow background highlight.

large payouts (abs > 2) should be colored in blue.

data that could be positive or negative should be colored in green or red foreground color respectively.

In my client’s case, there were three requirements: One of the more important customizations is to add colors depending on the data. I’ll skip these for now (interested readers can read all about them, and more, in my detailed uitable customization report). There are still quite a few other customizations needed here: enable sorting remove the border outline set a white background set row (rather than cell) selection and several other fixes that may seem trivial by themselves but together giver a much more stylish look to the table’s look and feel. tAutoResizeMode(jTable.AUTO_RESIZE_SUBSEQUENT_COLUMNS) Īuto-resized columns that actually work Third pass – adding colors We then use the setAutoResizeMode, as described in the official Java documentation. This is the containing scrollpane, and we are interested in the actual data table inside. We start by using the findjobj utility to get the table’s underlying Java reference handle. To solve the auto-resizing issue, we resort to a bit of Java magic powder. Second pass – auto-resizing that actually works… This causes only part of the information to be displayed on screen, and requires the user to either scroll right and left, or to manually resize the columns. This is apparently an internal Matlab bug, not taking HTML into consideration.

I have not done this here, but you can easily use HTML formatting for other effect such as superscript (), subscript (), bold (), italic (), font sizes and colors () and other standard HTML effects.Įven with the multi-line headers, the default column width appears to be too wide. I have already described using HTML formatting in Matlab controls in several articles on this website. We can see from this simple example how I have used HTML to format the header labels into two rows, to enable compact columns.
