One of the most boring jobs one can do in LATEX is to write a matrix or a tabular environment. One has to keep track of all the elements, ensure that the environment is well formed, and that all things are where they are supposed to be. Good indentation helps, but there is a simpler way: using Kile's → or → menu entries. You will then have a matrix-formed input form that you can easily fill in with your entries. This dialog also offers some options to typeset the tabular material.
Using the toolbar on top of the dialog you can set the
align of a cell, define a certain
split cells, choose a
border, and specify background and font
On the very right there is a Paste button. With this button you can insert a table
from the clipboard into the dialog, which allows you to copy and paste tables from a spreadsheet program, for example.
At the bottom you can choose how many rows and columns you want, and you can tweak some more things about your array:
With the Name option you can select which environment should be used for your array or tabular material.
You can select the vertical cell alignment with the Parameter option. This is only enabled for environments which support that feature.
If it exists for the selected environment, you can select use starred version. When you select this option, you also have to specify a table width.
Tables sometimes look nicer when you select the use booktabs package option.
Of course, you can also Center your whole array.
Inserting bullets helps you when you want to fill in your content in the editor. With this option checked, Kile will insert bullet placeholders for each element of your array.
The → option will display a simpler dialog to quickly set up a tabbing environment. It allows you to easily specify the number of rows or columns and the required spacing.
