The user should be able to set an input table as global. In other words, an input table could be defined later on or at the end of the document but the data would be available for the entire document.
The only way to accomplish that now is by defining individual global variables with arrays. However, especially when line spacing of arrays is not equal due to the data, or for long tables (more than a page), individual arrays are unruly.
This is useful when the data table is mostly filled with unneeded information, like these working load limit tables for different sized coil rods (commonly used in concrete formwork btw). (I put a 'globally defines table' notice on the table, just to see what it would look like, only a suggestion)
It's not long enough that I have it in a separate included file, but it's long enough that it would be better to be at the end of the document (it's only reference data). I could simply just enter the specific data for a rod size when I needed it for a calculation, but then I loose the whole functionality of making a reusable calculation sheet where I don't have to run to some external catalog every time I need a bit of data.
