table-backward-cell move point from the current cell to an
adjacent cell forward and backward respectively. The order of the
cells is cyclic: when point is in the last cell of a table, typing
M-x table-forward-cell moves to the first cell in the table.
Likewise M-x table-backward-cell from the first cell in a table
moves to the last cell.
table-span-cell merges the current cell with the
adjacent cell in a specified direction—right, left, above or below.
You specify the direction with the minibuffer. It does not allow
merges which don't result in a legitimate cell layout.
table-split-cell splits the current cell
vertically or horizontally. This command is a wrapper to the
direction specific commands
table-split-cell-horizontally. You specify the direction with
a minibuffer argument.
table-split-cell-vertically splits the current
cell vertically and creates a pair of cells above and below where
point is located. The content in the original cell is split as well.
table-split-cell-horizontally splits the current
cell horizontally and creates a pair of cells right and left of where
point is located. If the cell being split is not empty, this asks you
how to handle the cell contents. The three options are:
split splits the contents at
point literally, while the
right options move
the entire contents into the left or right cell respectively.
The next four commands enlarge or shrink a cell. They use numeric arguments (see Arguments) to specify how many columns or rows to enlarge or shrink a particular table.
