MantidPlot: add ability to resize columns of data tables using mouse

[Janik Zikovsky]

Under linux, at least, I cannot resize the width of data table columns. The number of digits displayed is too large and the exponent is never visible "1.0000e+..." is shown.

[Janik Zikovsky]

To clarify, my comment refers to the result of clicking "Show Data" on a workspace. Also; changing the table font in the Preferences has no effect.

Janik - to change the column width go to the Workspace menu item, then Set Properties... -> Cell Width. (Minimal) documentation at http://www.mantidproject.org/MantidPlot:_The_Workspace_Menu

This was added way before we touched the general MantidPlot preferences dialog, so I'll leave the ticket open because we may want to merge these options in with that.

Thank you, that works!

But I will change my suggestion: it would be more straightforward to resize the columns with the mouse, clicking between column headers and dragging. This is consistent with behaviour in Excel, File Explorer, etc. (almost all GUIs with column have this ability).

[Russell Taylor]

That's so obviously what we want to do, that I don't know why we didn't think of it before you suggested it! And it's just a flag on the relevant Qt object so it'll be done in a jiffy.

(In [4977]) Make columns in Mantid Matrix resizable by clicking/dragging in column header. Re #1338.

The feature works as advertised.
