Getting values from a dynamically sized table

Students can add rows to a table and can add content to each cell in the table.
Let’s say that I wanted to make a list and print out something like “The values you entered are {cell1}, {cell2}, … and ${last_cell}”

I’m having trouble finding something that lets me do this when I don’t know the size of the table in advance.

My current workaround plan is to fix the table at a length of 10 and take any non-empty cells, but I would like to be able to get a source of the number of rows / number of columns when students are allowed to add rows/columns.

Any advice?

maxRows
Sets the number of rows the table will display.

maxRows is a sink not a source :frowning:

If it is just numeric values that are being entered into the cells, you could probably do this with columnNumericValues, which turns the values into a list that you could then process further in a graph component or within the CL. For instance, length = this.columnNumericValues(2).length should give you the number of values in the second column, or in a graph component something like numberList("X"): table1.columnNumericValues(2) would inject the table column as a list in the graph for further processing.

Does that help?

Here’s my version. I’m using the hidden graph to sort out undefined cells (for when a student goes back a deletes an entry). Note that these are the decimal numeric values of the cells, NOT the actual cell entry. I then have some conditional statements for the text in the note. Let me know if you have questions about some of the use of ${} in the text.

I need to be able to grab text, not just the numeric value.

This is my current use case: Declare a C# Variable • Activity Builder by Desmos Classroom

and I’m currently using a limit of up to 10 list items and have hardcoded my string concatenation.

I’ve got it working with number-only expressions. You could do it with text, but it’ll get fairly complex because you’ll have to define individual evaluated simpleFunctions with all letters as variables.
