After you have created a table (see Tables) you can to edit it in a number of ways, including entering or deleting data, adding or removing row or columns, splitting or merging cells.
Edit the data in a cell by selecting the relevant cell and editing just as you would in the body of the document i.e. typing to enter data, backspacing to delete data. Delete the entire contents of a cell by selecting the contents with your mouse and pressing the Delete key (or right-clicking and selecting Cut).
Format a cell, row, column or group of cells by first making the appropriate selection and then applying the formats in the usual way. Select a cell by clicking on it; a row by moving the mouse pointer to the left of the table, on the same level as the row, and clicking once when the pointer turns to an arrow; a column in the same way as for a row but moving the pointer above the column. To select a group of cells, rows or columns, follow the above procedures but keep the Ctrl key on the keyboard depressed. This prevents a later selection from canceling an earlier one.
The following commands are available through the Table menu (or from the drop-down menu when you right-click your mouse):
Insert Rows allows you to insert a row, with the option of choosing to insert the row above or below the currently selected row. You can also choose how many rows to insert.
Insert Columns allows you to insert a column, with the option of choosing to insert the column to the left or the right of the currently selected column. You can also choose how many columns to insert
Delete Rows allows you to delete selected rows. Access this through the Delete command in the Tables menu. Select a row to be deleted by clicking in any cell in that row.
Delete Columns allows you to delete selected columns. Access this through the Delete command in the Tables menu. Select a column to be deleted by clicking in any cell in that column.
Delete Table allows you to delete a whole table. Access this through the Delete command in the Tables menu. Select a table to be deleted by clicking in any cell in that table.
Merge Cells allows you to merge selected cells. The cells must be adjacent and form a complete rectangle or square before the command is activated. The selected cells will then be formed into one big cell, with the individual cell borders erased.
Split Cell allows you to split a cell into several smaller cells. In the "Split Cell" dialog box you can choose how many rows (between 1 and 30) and columns (between 1 and 10000) to split the selected cell into. Note that the cell to be split may be a cell that was previously created by using the Merge Cells command.
Split Table allows you to split a table into two parts. Before selecting the Split Table command, you need to select a row (or any cell in the row) at which to make the split. The table is split so that the rows above the selected row form one table and those below, along with the selected row, form the second table.
Join Table allows you to join separate tables into one table. First, select the topmost of the two tables to be joined (note that you need only select a row or a cell in the table). On applying the command the selected table is joined to the table beneath it. If there is some intervening text between the tables in the main body of the document, this is placed after the new joined table.
