3 Improvements of the Table controls

[G_Mulder]

The Table is an important UI feature allowing cell widths adapted to the contents (a bit like in Excel). That is much better than the rigid array front elements. It is also much more powerful since cells can be coloured, cell fonts can be changed, cells can be highlighted and still more. Some possibilities appear to lack:

1 There is no 1D version of it. This necitates the user to finely adapt the height to see only one row. This makes that no dark grey line is around it and a user can accidently change to lower lines by selecting a cell and some mouse operation. It is hardly possible to return backward, certainly if the user is not aware that the line is in reality a 2D field.   Under properties e.g.' 1 row, 10 columns' can be given, but that does not prevent changing to other rows. For arrays dimensions can be added (from 1 to many), for the table dimensions 1&2 would be helpful.

2 Cells can be indicated with help of the properties 'selection start', 'selection size' and 'selection color'. The selections can not be programmatically disabled and re-abled when needed. At least a corner element remains if the 'selection size' is reduced to (0,0). With the right-click menu options a 'show selection' option exists for enabling and disabling the feature. It lacks as a property node.

3 Cells can be coloured with help of property node calls, what is nice. The method to undo all colourings and other settings does not exist. The invoke node method 'reinit to default' has no influence on the individual cell fonts, cell colours, etc. An invoke node to reset these features is wanted as well in addition to the existing reinitialisation. This lack is preventing using these features since the changes should be kept in memory somewhere to undo, or all cells have to be overwritten periodically with a lot of code. If the table length is undefined since e.g. measurement data  is put into it, then an arbitrary number of rows have to be assumed. A reset function can take this trouble out of hands.

The same remarks hold probably for the listbox controls.

Of course it does! You can select negative numbers to select everything, see the help. e.g. an Active cell of [-2,-2] selects all cells, including headers. Now just set the color to white.

[-1,-1] selects all cells while [-2,-2] selects all cells plus the headers.
