The default style is ugly. Can I change it?

Yes, if you're able to change your theme's style sheet. The plugin renders HTML with plenty of CSS hooks. Use the igsv-table class from your style sheets to target the plugin's <table> element.

Additionally, each row (<tr>) and cell (<td>) is assigned a specific class attribute value. The first <tr> element is assigned the row-1 class, the second is assigned row-2, and the last row-N where N is the number of rows in the rendered table. Similarly, each cell is assigned a class based on its columnar position; the first cell in a row is assigned the col-1 class, the second col-2, and so on:

.igsv-table .row-2 .col-5 { /* styles for the cell in the 2nd row, 5th column */ }

Finally, both rows and cells (based on columns) are assigned an additional class of either odd or even, allowing for easy zebra-striping in CSS3 non-conformant browsers.

.igsv-table tr.odd  { /* styles for odd-numbered rows   (row 1, 3, 5...) */ }
.igsv-table tr.even { /* styles for even-numbered rows  (row 2, 4, 6...) */ }
.igsv-table td.odd  { /* styles for odd-numbered cells  (column 1, 3, 5...) */ }
.igsv-table td.even { /* styles for even-numbered cells (column 2, 4, 6...) */ }

A table appears, but it's not my spreadsheet's data! And it looks weird!

You should triple-check that you've published your spreadsheet. Google provides instructions for doing this. Be sure to follow steps 1 and 2 in Google Spreadsheets Help: Publishing to the Web.

Can I remove certain columns from appearing on my webpage?

While you can't strip out columns like you can do with rows, you can hide columns using CSS with code such as, .col-4 { display: none; }, for example.
