<p><bold>Figure 1. Examples of how to restructure two common issues with tabular data</bold>. (a) Each cell should only contain a single value. If more than one value is present then the data should be split into multiple columns. (b) There should be only one column for each type of information. If there are multiple columns then the column header should be stored in one column and the values from each column should be stored in a single column.</p>
