As far as I can tell, these display selectors seem to be identical.
From the Mozilla CSS documentation:
inline-table: The inline-table value does not have a direct mapping in HTML. It behaves like a <table> HTML element, but as an inline box, rather than a block-level box. Inside the table box is a block-level context.
inline-block: The element generates a block element box that will be flowed with surrounding content as if it were a single inline box (behaving much like a replaced element would).
It seems that whatever could be done with inline-table can be done with inline-block.
display:table will make your tag behave like a table.
inline-table just means that the element is displayed as an inline-level table. You can then do table-cell to let your element behave like a <td> element.
display:inline - displays your element as an inline element (like <span>), and inline-block will just group them together in a block container.
As the other answer suggested you can replace between the two as long as you follow the display convention in the rest of your code. (i.e. use table-cell with inline-table and not with inline-block).
