For an additional challenge, modify the script so that each output and input address has its own cell. We recommend approaching this by determining the maximum number of input values or output addresses in a list of transactions. Knowing these values, you could build a conditional statement to modify the header so that it has the appropriate number of columns. In addition, you would need to write logic to skip those columns when you don't have multiple input or output values in order to preserve the correct spacing of data.
While specific to Bitcoin, examples in the wild may require similar logic when there exists a dynamic relationship between two or more data points. Tackling this challenge will help develop a logical and practical methodology that can be applied in future scenarios.
