Unfortunately, if it is formatted as a table then you cannot merge cells in the data range. If it is not necessary to have the table formatting, then you could convert it to a range instead - click somewhere inside the table, then select the Table tab from the ribbon. In the Tools group, select 'Convert to Range'. You will then be able to merge the cells.
Would that help or do you need to keep the table formatting?
A 'table' in Excel is sortable - it has drop down boxes at the top of each column allowing you to filter the data. Therefore if you were to merge cells together it wouldn't be able to to this, which is why it doesn't allow you to merge cells in a table.
A 'range' is just a group of data.
You can tell whether you have a table or a range by clicking inside the data and seeing if the 'Table Tools' tab appears on the ribbon.
