Final answer:
A tabular Custom Report displays a sortable table with rows of data, which is ideal for analyzing and comparing different tactics based on specific data points.
Step-by-step explanation:
The type of Custom Report that shows a tactic, sortable table with rows of data is a structured, tabular report. Tables are highly efficient for presenting detailed datasets in a format that allows for quick scanning and analysis. Unlike pie charts or other visual graphs, tables do not inherently prioritize one data point over another but offer a democratized view of all data points. This type of Custom Report is essential when you want to analyze different tactics based on various metrics, which can then be sorted to help identify trends or outlier values within the data.
