[LFC][TFC] Introduce TableGrid

[zalan]

Table grid -> A matrix containing as many rows and columns as needed to describe the position of all the table-rows and table-cells of a table-root, as determined by the grid-dimensioning algorithm.
Each row of the grid might correspond to a table-row, and each column to a table-column.
