It’s not bad, but it suffers from a problem that afflicts many tables: it shoe-horns column headings into single cells. For instance, near the middle of the table, one column heading has the words 'Drunken Acts - Staff' all within a cell that sits atop a series of numbers.
This creates two problems:
IFUTRTI (‘It Forces Us To Resort To Initialisms’). Long labels don’t fit well in single cells, so we resort to initialisms – and I’ve seen dreadful ones: “% change in PY CQTD Fct 23 v Act 22” (what the heck?!?). OK granted, Figure 1 thankfully avoids initialisms (other than 'ID'), but shoe-horning stuff into single cells creates an arguably bigger problem.
Readers struggle to grasp structure. When readers’ eyes first land on Figure 1, they think: “Ah… ten columns of data”, then after scrutinising it for a bit, they realise: “No, wait… one group of two, another group of three, then a group of two… then a single column, etc”. Figure 1 forces readers to work out such groupings for themselves. (This problem arises constantly in Finance packs where tables are a right royal mix of columns - 2023, 2022, Actual, Budget, Var, £, %, YTD, Month.)
Instead, straddle column headings over the common columns to which they relate. Readers more easily grasp structure and groupings – they spot similarities where stuff is similar, and spot differences where stuff is different. Readers more quickly acclimatise to the table.
See Figure 2 (again, it’s just the three most recent months).
