Thanks, that solves my problem. I had not noticed the possibility of inserting a Spreadsheet from the menu, sorry! Now it works acceptable.

Some comments: I am writing a guide for my students. At the same time I am trying to find out the best working process for them. It seems like it is not possible to access data from within the Spreadsheet outside it on the command lines. I mean you cannot reference the data in the cells in the Spreadssheet outside on the command lines. So I guess when making plots from data it is better staying outside the Spreadsheet and doing everything on the command lines. The spreadsheet can on the other hand serve as a graphically better way of presenting things than what is possible on the commandlines. My applications are in Physics. Often we use The Logger Pro software from Vernier for data collection from physics experiments. Inside this program it works like a spreadsheet: Some columns are measured, others can be calculated and it is very easy producing plots from the columns. Basicly you just insert a graph and point out which data columns are going to be on each axis. I was investigating how Maple was working here. Apparently not as userfriendly, but still acceptable for some applications. On other issues Maple is far ahead when talking about doing manipulations to data and analyzing it ...

It does not work! If I put a # at the beginning of the line and press the execution button, the Spreadsheet disappears completely.

Thanks! This Spreadsheet works a little like Excel indeed. However when I accidentally execute your command line after having worked with the Spreadsheet, all data disappears. Is there a way to prevent a line of being executed when the entire worksheet button is being used?

Thanks again Georgios. I appreciate your response and I have read the thread you linked to quite thoroughly. It had some interesting points for sure, but I also got the impression that this question doesn't have an easy answer in Maple, unless that thread was outdated? To be honest I am looking for a more easy and straight-forward way. Maybe I should describe my background a little: I am a high school Teacher from Denmark with a degree in mathematics and physics, comparable to a masters degree with thesis. I have introduced Maple to our high school, and we finally purchased a school license last spring. My physics students are happy about it and very interested and enthusiastic, and so am I. I am still searching for new possibilities in Maple - obtainable for high school students - and this time the subject is: Tables. It is not a key point for us, but still it would be nice if it worked well. 

I really hope Maple will follow the road of more userfriendly interface as was initiated in version 10, I have been told. This is crucial for a broader audience, I think. In combination with their favourable license politics it could mean a step in front of Mathematica and the other alternatives like MathCad.

NB! I maintain my own Danish homepage about mathematics, it contains however one page written in English: http://www.matematiksider.dk/enigma_eng.html

Hi Erik Postma

Thanks a lot for pointing out to me the exact Palette I was looking for. I am happy to see that the symbols I requested are already in Maple! I am sorry I didn't spot this by myself. I am however grateful because of this MaplePrimes forum. I am sure it can help me more in the future.

There is no problem with xy. The students know it means a new variable xy and not x times y. It is the same with Texas 89. I am trying to introduce Maple, because fewer and fewer danish students thinks it is very smart to first make calculations using Texas 89 and then write the results on paper - especially the guys! I can report no problem with sin(x) either. The 2D math notation is important, though!

2D input and palettes are two different things, I know, but they both add to the usefulness for newcomers to Maple, especially students. I too like to let my hands stay at the keyboard and avoid the many clicks as much as possible.

The palettes in MathType do cover about 99.5% of all symbols needed for - I guess - all science people all over the World. I mean one lucky thing is that the symbols of mathematics are pretty much universal. So I simply can't follow your argument that some people in other countries use different symbols. I know some University mathematicians deeply buried in special areas of mathematics might miss some symbols. They typically use LATEX. So the set of palettes maybe can't cover any possible symbol, but still I think they will be of great use. However I don't understand why Maple don't have "He-4-2" prototypes in their palettes. That symbolism is pretty basic. Maybe they will in version 14? :)

What I understand from your comments is that you think that the palettes are poorly implemented? That there is not always a corresponding code to every symbol in the palettes. Is that correct? If so I can understand if you are not satisfied. I will try to investigate some of you guys links.

I am not completely aware of what you mean, since I haven't followed the discussions you refer to (I am rather new to MaplePrimes). Many Danish students today are badly trained in the use of the hierarchy of the basic four operations +, -, * and /, så when they for example want to write a fraction with x in the numerator and y+z in the denominator, many will write just x/y+z and not x/(y+z) which is the right way. When using Maple notions (1D) they will make the same mistakes. Using Maple 2D notation they will discover their mistakes and write it correctly in the second try. That's why I like Maple having adapted this notation ... I think it was in version 10 or so, right? ... Also the palettes adds to the usefulness for people who are not too strong mathematically. 

On the other hand, I think many people will try to learn more and more code, when moving on in Maple. Often it is more easy and you don't need all the clicking ...

I have read somewhere that the document mode is pretty new to Maple. I have left it though and returned to Worksheet Mode, because it is easier to control and I like that one can see, which problems Maple have solved (indicated by the red arrow) and which parts of the document is plain formula writing by the user (placed in text lines). In document mode it seems to get mixed up!
