Hello Gary

Thank you for your purchase.

1. You can change font settings in main settings of wpDataTables/Color and Font settings:

2. Yes, this would be possible with some simple CSS.

It should look something like this:

.wpdt-c th.column-newcolumn {
white-space: normal !important;
width: 200px !important;
}

Where "newcolumn" is the column's name from the database. You can see this when you open the settings of that column:

3. This can also be done with some CSS. You need to find the column name in the column settings:

Then add the following CSS:

.wpdt-c th.column-product {
background-color: red !important;
}

My test table has columns "Name", "Product", "Date" and "Image", so my CSS would look like this:

.wpdt-c th.column-name {
background-color: gray !important;
}
.wpdt-c th.column-product {
background-color: red !important;
}
.wpdt-c th.column-date {
background-color: blue !important;
}
.wpdt-c th.column-image {
background-color: wheat !important;
}

And the outcome would be:

If you want to apply this to all tables, you can paste the CSS in Custom CSS field in Custom JS and CSS tab in main settings of wpDataTables. If, however, you wish to apply this only to a certain table on front-end, you need to add it when you're creating the page, above the shortcode, in between the <style>...</style> tags, like this:

<style>
.wpdt-c th.column-name {
background-color: gray !important;
}
.wpdt-c th.column-product {
background-color: red !important;
}
.wpdt-c th.column-date {
background-color: blue !important;
}
.wpdt-c th.column-image {
background-color: wheat !important;
}
</style>
[wpdatatable id=1]

4. Again, this would be possible with some custom CSS. For example:

a.dt-button.buttons-print.DTTT_button.DTTT_button_print {
color: green !important;
}
a.dt-button.buttons-excel.buttons-html5.DTTT_button.DTTT_button_xls {
color: red !important;
}
a.dt-button.buttons-csv.buttons-html5.DTTT_button.DTTT_button_csv {
color: blue !important;
}
a.dt-button.buttons-copy.buttons-html5.DTTT_button.DTTT_button_copy {
color: orange !important;
}

And they would look like this:

You can also use the same logic on "Add new", "Edit" and "Delete" buttons. The selectors would be:

a.dt-button.new_table_entry.DTTT_button.DTTT_button_new
a.dt-button.disabled.edit_table.DTTT_button.DTTT_button_edit
a.dt-button.disabled.delete_table_entry.DTTT_button.DTTT_button_delete

To style the search button, you can add something like this:

div#table_1_filter {
background-color: aqua !important;
}

So it looks like this:

5. When you access your table, simply click on this field in top left, and enter a new name:

6. Unfortunately, there's no way to add a template, but you can duplicate the tables from the tables' list:

If you're creating manual tables, please make sure to leave the slider that comes up when you click on "Duplicate" enabled. It will create a new copy of that table in the database, so you don't lose any data from the first table when modifying its copies.

7. You can change columns' width if you enable "Limit table width" in the "Display" tab above the table. When you do that, each column will have a "Column Width" feature:

Unfortunately, dragging and resizing columns like that is not yet possible with the plugin's built-in features. Our developers do have that on their "To-Do" list, but I cannot say when or if it will be implemented. Microsoft Excel is a product that has been developing for over 30 years by Microsoft, and it is extremely powerful. wpDataTables is simply a WordPress plugin, and it doesn't have nearly as much features as Excel.
