I was reading the tabularx documentation and stumbled over a few things unclear to me.
In 4.3. Point 1 suggests that the the sum (of the fractions before
\hsize) should always be the number of columns used. Will it do any harm if this does not fit (except that if you calculated the numbers in advance, the columns width won't exactly fit the calculation (I'm asking just, because sometimes you do the maths but then you think that one column should be a bit bigger, so one just want to increase that one number instead of recalculating everything))
In 4.3. Point 2: What is meant by crossing? Should one have no multicolumn
[lXl](going over the left and right bound of a
[XX](spanning over multiple
Xcolumns) or even
Xcolumn)? - And why is that a problem, when the size does not fit, the package will just recalculate the sizes (from my understanding)
\hsizebe used to "weight" the column width and not another length like
\linewidth(from what I know, they are somewhat similar (and on most occasions the same)?
