The Cell Properties menu box will open, showing you a number of ways to change the appearance of the numbers, and the number of decimal places to be printed. This can make all the difference between a table which is too wide to fit on a printed page and one which fits comfortably. You can help the computer to do this effectively by making sure that every word in each label is fairly short - a column can't generally be narrower than the shortest word in a label. Here's a table before autofitting and here it is afterwards. As you gain experience with SPSS you will realise that careful choices of the names and value labels of variables is very important.
Tables look untidy if the margins are filled with excessively long and fussy labels.
If SPSS doesn't have enough room to insert all of a label it will stop when it runs out of space. The chi-squared test is appropriate for this data. By the usual convention, if p is less than 0.05 the table counts as significant. Most people just want to know whether p is less than 0.05 or not. Calculated values of 0.40 is much too large to be anywhere near significance, and 0.000 is so small that the true figure is almost certain to be significant.
