Visibility coloration in table wrong for rows with Nans

[pjcross]

I think that we must be using the same table coloring rules for Parameter Space as we are using for CCA, which provides the mistaken impression that any row with a Nan in a column that has been declared as either an input or an output is not visible. Unlike CCA, a row with a Nan is not automatically filtered out by virtue of the Nan in an input or an output column. That row should have the usual green/purple/white color-coding for the input/output/neither columns. Since we are using a white row to show non-visibility due to filtering, the visible row with a Nan looks much like the non-visible, filtered out rows around in the example above. Only the faded text shows the difference. There are only two cases where having a Nan in the row should make a difference to the color-coding: (1) if the column with the Nan is being used as an axis in the scatterplot, this row can not be shown due to the lack of a coordinate value (2) if the column with the Nan is one of the filters and NULL values are not enabled. It seems to me that although neither case reflects an explicit removal of these points, they are essentially non-visible points and should be colored using the same scheme as any other non-visible points (white rows with faded text). The case of white row with regular black text should not occur unless all columns are defined as 'neither'.
